Frequently Asked Questions

Yes, absolutely! Pizzaformule.nl is built as a modern Progressive Web App (PWA). This means you can install the website directly onto your phone (iPhone and Android), tablet, or desktop computer with a single tap — without going through the Apple App Store or Google Play Store.

A very fair question. Many online calculators and cookbook recipes are built on simplified charts or rigid rules of thumb that ignore how dough behaves in the real world. The fundamental difference is that Pizzaformule.nl is not an opaque 'black box' of rough guesswork; it is rooted in official international Neapolitan craftsmanship, reinforced by modern dough biochemistry and oven thermodynamics.

You do not need expensive commercial equipment to start. A digital kitchen scale (measuring to 1 gram), a spacious mixing bowl, and your standard domestic oven are plenty. Even better is a precision pocket scale accurate to 0.1 g or 0.01 g: in controlled, slow fermentations, yeast is often dosed in fractions of a gram (such as 0.44 g). Pizzaiolo tip if you lack a 0.01 g scale (the 1-in-100 dilution method): dissolve 1 gram of yeast in 100 grams (100 ml) of water and stir well. Each gram of this solution contains exactly 0.01 g of yeast; for 0.44 g of yeast, simply weigh out 44 grams of this yeast water. Always take this water from your already weighed recipe water (or subtract those 44 grams from your total water) so your dough hydration stays exact! An inverted baking sheet preheated for at least 45 minutes on your oven's highest setting also produces surprising results.

If you want a major leap in crust crispness and oven spring, a baking steel or pizza stone is the very best initial investment you can make.

That depends entirely on your recipe and timeline. The Italian designation Tipo 00 indicates only the milling grade (pure white, finely ground flour with bran removed), not protein quality or baking strength (W index).

Standard all-purpose or patent flour typically has 10% to 11% protein (~W180-200). This works well for simple doughs with short proofing times (4 to 8 hours) and moderate hydration (up to 60-62%). However, if you plan a multi-day cold fermentation in the fridge (24 to 72 hours) or high hydration (65%+), your dough requires a stronger flour with at least 12.5% to 13.5% protein (W280-320), such as dedicated pizza flour or Manitoba, to keep the gluten matrix from degrading.

Short answer: most retail flour packaging in supermarkets does not state the W index.

Manufacturers are legally only required to print a standard nutritional table (carbohydrates, fats, protein, and salt). The W value (baking strength, measured with a standardized Chopin Alveograph) is an industrial laboratory metric. Millers traditionally printed this specification only on 25 kg sacks for commercial bakeries and pizzerias. A few specialty Italian pizza brands (such as Caputo or Le 5 Stagioni) now print the W value directly on consumer 1 kg bags.

This is purely a matter of oven thermodynamics. In a dedicated pizza oven (450°C to 500°C / 840°F to 930°F), a Neapolitan pizza bakes in just 60 to 90 seconds via intense radiant and conductive heat. Oil and sugar are forbidden because they burn acrid and bitter at those extreme temperatures.

In a domestic home oven (220°C to 275°C / 430°F to 525°F), baking takes 6 to 10 minutes via convection. Without additives, moisture evaporates too slowly and the crust turns pale, tough, and dry. A splash of extra virgin olive oil (1.5-2.5%) conducts heat into the crumb and keeps dough tender. A touch of sugar, honey, or malt extract (1-1.5%) stimulates the Maillard reaction, delivering a beautiful golden crust even at moderate home oven temperatures.

Yes, absolutely. Instant dry yeast (IDY) consists of live yeast cells placed into dormancy by manufacturers in protective, low-oxygen packaging. Once opened, the yeast immediately comes into contact with oxygen and ambient humidity.

In a commercial pizzeria, yeast packets are consumed daily. At home, however, an opened jar or sachet often sits in the pantry for weeks or months. Over time, a significant fraction of yeast cells dies off: after a few weeks, yeast can lose 10% to 25% of its rising activity. If you dose using exact calculator numbers, fewer viable cells are active than calculated, resulting in noticeably slower fermentation.

Baker's advice for maximum yeast vitality:

• Airtight in the freezer or fridge: Store opened yeast airtight (in a small glass jar or sealed ziplock bag) inside the freezer or refrigerator. At sub-zero temperatures, yeast cells remain in deep hibernation, preserving virtually 100% viability for months. Granules thaw in seconds once whisked into flour.
• Choose small sachets: If you don't bake weekly, buy small individual 7g sachets rather than large tins so you always open fresh yeast.
• Compensating for older yeast: If an opened packet has been stored at room temperature for months, add 10% to 15% extra to offset inactive cells, or proof a pinch in lukewarm water with a speck of sugar to verify vigorous foaming.

The universal baker's conversion ratio between instant dry yeast (IDY) and fresh cake yeast (CY) is 1 to 3:

• Dry yeast to fresh yeast: Multiply grams by 3 (e.g. 1 g dry yeast = 3 g fresh yeast).
• Fresh yeast to dry yeast: Divide grams by 3 (e.g. 6 g fresh yeast = 2 g dry yeast).
• Active dry yeast (coarse granules needing rehydration): Multiply by 2.5 (1 g active dry yeast = 2.5 g fresh).

The supermarket pitfall of "1 packet of yeast (7g / 0.25 oz)":
A standard supermarket packet contains 7 grams of dry yeast, equivalent to 21 grams of fresh yeast. Manufacturers formulate this dose for 1 kilogram of heavy wholemeal bread dough forced to double within 45 minutes. For authentic pizza dough with an 8 to 24-hour slow fermentation, you only need 0.2 to 0.8 grams of dry yeast per kilogram of flour! One single 7g packet is enough for 10 to 15 Neapolitan pizzas. Dumping an entire packet into dough for 2 to 4 pizzas will result in an acrid yeasty flavor, heartburn, and bloating.

Dealing with a store recipe calling for too much yeast? Use our Slow-down tool to convert it into a digestible, slow cold fermentation.

Absolutely! In the advanced settings of the Pizza Calculator, you can check Add whole wheat flour and use the slider to blend in 1% to 20% whole wheat flour.

We recommend a maximum of 20% whole wheat flour because the sharp bran and germ particles cut into the delicate gluten strands. Above 20%, pizza dough rapidly loses elasticity, resulting in a denser, less airy crust with limited oven spring.

Our calculator automatically compensates for whole wheat flour at two crucial biochemical levels:

• Automatic water compensation (+15% on whole wheat): Bran particles absorb significantly more water than refined white flour. To ensure your dough retains the exact same supple, workable texture as your target hydration, the calculator automatically adds 15% extra water calculated over the whole wheat flour weight.
• Yeast adjustment (-0.50% per 1% whole wheat): Whole wheat flour contains abundant minerals, enzymes (amylases), and natural micronutrients that accelerate fermentation. The calculator proportionally dials back yeast (up to 10% less yeast at 20% whole wheat) to prevent premature over-fermentation.

Baker's tip for preferments (Biga or Poolish): Whole wheat flour is always kept 100% in the final main dough (step 2). Preferments demand maximum enzymatic stability and the pure gluten strength of white flour.

You do not need a machine at all. Hand kneading is magnificent for virtually every recipe in this calculator. In fact, kneading by hand teaches you how dough develops; you immediately feel when gluten strands align and surface tension builds.

By utilizing an autolyse (letting flour and water rest before kneading) and the stretch and fold technique, the gluten framework forms almost autonomously without tiring effort or machine friction heat. Heavy-duty spiral mixers only become essential when processing large batch sizes or high hydrations above 70%.

Never add extra flour! Doing so destroys your calculated hydration and salt percentages, yielding a heavy, dense, and tough crust.

Instead, apply the professional baker's remedy: give the dough time to rest. Invert a bowl over the dough and leave it alone for 10 to 15 minutes. The starch granules will absorb water into their core and gluten tension will relax. Afterward, work with lightly damp hands or a drop of olive oil on your fingertips. You will find that previously unmanageable dough has transformed into a smooth, supple, and cohesive mass.

Baking very high hydration dough (75% to 85%), such as in our Focaccia Calculator? Techniques like stretch and folds performed in a lightly oiled bowl are essential to develop gluten strength without adding any extra flour.

At hydration levels above 68% (and especially for focaccia at 75% to 85%), traditional counter kneading is nearly impossible: the dough sticks aggressively and puddles flat. Instead of adding raw flour, artisan bakers use folding techniques. By gently stretching and folding the dough onto itself, you align gluten strands in overlapping layers. This creates strong elasticity and surface tension without crushing fragile gas bubbles.

The baker's routine: Perform 3 to 4 sets spaced 20 to 30 minutes apart. The dough relaxes between sets and gains compounded structural strength with each round.

To achieve the target dough temperature after kneading (DDT: Desired Dough Temperature), bakers calibrate the temperature of the mixing water. The universal thermodynamic formula is:

The traditional Baker's Rule of 55 (hand kneading) or 60 (machine kneading) is a simplified shortcut derived from this equation, assuming a static target of 23°C to 24°C (73°F - 75°F) for direct room-temperature fermentation.

Our Pizza Calculator and Focaccia Calculator dynamically calculate your DDT and required water temperature based on your fermentation schedule, fridge temperature, hydration, and kneading method. The recipe sidebar displays this advice rounded to clean whole degrees, including an ice water alert when extra dough chilling is necessary.

At room temperature, yeast multiplies far faster than enzymes can ripen the flour. The dough inflates with gas before nuanced aroma can form.

In the refrigerator (4°C / 39°F), yeast activity is stalled while natural enzymes (amylase and protease) work steadily. This process is called maturation. Enzymes break complex starches into simple sugars and cleave heavy proteins into amino acids. After 24 to 72 hours, the result is deep aroma, golden crust coloration, and a pizza that is remarkably light and easy to digest.

Effortless stretching & zero snapback: Just as important is the physical transformation. Over extended cold maturation, proteases gently soften gluten tension. The stubborn elasticity (where dough constantly snaps back like a rubber band) vanishes. Dough balls stretch out paper-thin with ease, while air bubbles migrate freely into the puffed rim.

Use the traditional finger poke test: press a floured fingertip about 1 cm into a dough ball:

• Under-proofed: The indentation springs back immediately and forcefully. The gluten network is still tense; allow more time to relax.
• Perfect peak: The dent gently and slowly rebounds halfway. The ball feels silky, soft, and aerated. Time to bake!
• Over-proofed (proteolysis): The dent remains completely or the ball gently deflates. The dough smells sour or alcoholic and is very sticky. Because enzymes have broken down the gluten matrix too far, the dough will tear easily during stretching.

Many conventional cookbook and blog recipes are designed around rushing: they prescribe excessive yeast (often an entire 7g sachet or half a block of fresh yeast for just 500g of flour) to force dough to double within an hour. While this produces fast volume, it leaves an unpleasant yeasty taste, a dense crumb, and causes bloating because the flour never had time to mature enzymatically.

With the Slow-down tool, you transform hasty recipes into exquisite slow fermentations. Enter the ingredients of your existing recipe and select how much time you actually want to give it (for example 8 hours at room temperature or 24 to 48 hours in the fridge). The calculation engine immediately reduces the yeast dosage — often down to less than 1 gram! This eliminates yeasty aftertaste, relaxes the gluten for easy stretching, and produces a light, crispy, and deeply flavorful crust.

A rolling pin crushes the precious carbon dioxide gas bubbles that yeast worked hours to generate. The result is a dense, flat, and chewy disc devoid of lightness.

Pizza dough should always be opened by hand: press flat finger pads from the center outward. This gently massages gas towards the outer rim, where it will expand explosively under oven heat into that coveted, crisp, and airy cornicione.

A stuck pizza accordioning onto the hot baking stone into an accidental calzone is every home baker's nightmare. Follow these three proven rules:

• Use semola rimacinata: Dust your bench with finely milled durum wheat semola instead of plain flour. Spherical semola grains act like microscopic ball bearings beneath the dough and will not scorch bitter in the oven.
• Top swiftly and moderately: Once wet sauce and fresh mozzarella touch the dough, moisture begins seeping through. Finish topping within 60 to 90 seconds and pull onto the peel without delay.
• The shimmy check: Give the peel a gentle back-and-forth shake just before launching into the oven. Does the pizza glide freely? If so, launch with confidence. If a corner catches, lift it and blow a puff of air or dust a pinch of semola underneath.

The distinction comes down to thermal conductivity:

• Baking steel: The undisputed champion for domestic ovens (up to 275°C - 300°C / 525°F - 575°F). Steel conducts heat up to 18 times faster than stone, giving the crust an instant thermal shock (oven spring) for a crisp undercarriage.
• Pizza stone (cordieriet): Ideal for semi-commercial ovens between 300°C and 400°C (575°F and 750°F). Stone stores significant heat but transfers it more gradually, preventing the bottom from scorching before toppings cook through.
• Biscotto clay stone: Essential for high-heat pizza ovens running at 450°C to 500°C (840°F to 930°F). Handcrafted clay tiles from Naples have very low conductivity, allowing a 60-second bake without charring the bottom black.

In dedicated gas, wood, or electric pizza ovens (such as Ooni Koda/Karu, Gozney Roccbox/Dome, Effeuno, or a Kamado BBQ), temperatures range from 400°C to 500°C (750°F - 930°F). A Neapolitan pizza bakes in just 60 to 90 seconds. This extreme heat requires specific formula adjustments:

• Zero sugar, malt, or oil in the dough: Above 350°C (660°F), added sugars and fats scorch instantly, creating an acrid, bitter black crust before the inner crumb can bake through. Always choose the Neapolitan preset in our Pizza Calculator (which automatically disables oil and sugar) or manually toggle them off.
• Controlled hydration (60% to 65%): In a regular domestic oven, high hydration prevents dough drying out during 8-10 minute bakes. In a 90-second inferno, steam cannot escape fast enough from over-hydrated dough (above 68%), leaving a gummy raw interior. 60% to 63% is the golden standard.
• High-strength flour (W280-W320): Genuine Italian Tipo 00 flour (such as Caputo Pizzeria or Cuoco) withstands extreme radiant heat without scorching due to its finely milled starch and elastic gluten profile.
• Measure stone temp with an infrared thermometer: Ensure your baking floor is at least 420°C to 450°C (790°F - 840°F) before launching. Rotate the pizza a quarter turn after 30 seconds for even leopard spotting (leoparding).

Unlike free-form pizzas, pan breads like focaccia require an exact relationship between pan surface area and dough weight. Our Focaccia Calculator uses the verified baker's formula:

Because high-hydration dough (78% water) loses approximately 10% to 14% moisture through evaporation during baking, we apply calibrated artisan factors:

• Classic Genovese (0.60 g/cm²): For a golden-brown, crispy focaccia about 1.5 to 2 cm tall with deep olive oil-rich dimples.
• Focaccia Alta (0.75 g/cm²): For a traditional fluffy Italian sheet focaccia about 2.5 cm tall with generous alveolar air pockets.
• Sandwich / Extra Tall (0.95 g/cm²): For a towering focaccia (3.5 to 4 cm tall) with resilient gluten walls, engineered for slicing horizontally into sandwich loaves.

The mathematical engine then derives all individual ingredients (100% flour, 78% water, 4.5% olive oil, 2.5% salt, and yeast) from this total dough mass using baker's percentages. Additionally, the tool enforces a safety floor of at least 10 grams of pan oil per baking tin so the dough never sticks to the corners of smaller home pans.

While both Ligurian focaccia and Tuscan schiacciata are dimpled flatbreads baked in oiled sheet pans, their baking philosophy and crumb texture are fundamentally different:

• Focaccia (e.g. Genovese): Focuses on a tender, pillow-soft, and juicy crumb. Right before baking, the dough is drenched in a salamoia—an emulsion of water, extra virgin olive oil, and fine salt. The water settles into the dimples and slowly steams in the oven. This dampens crust formation, keeps the crumb velvety, and creates the classic contrast between golden hills and soft, pale dimples.
• Schiacciata (Tuscan / Florentine): Focuses on crispness, blistered bubbles, and shattering crunch. Here, bakers intentionally add zero water (and thus no salamoia) to the surface. It is dressed solely with generous pure extra virgin olive oil and coarse sea salt flakes. In a hot oven (240°C–250°C / 465°F–485°F), the pure oil instantly sizzles, effectively frying the crust to deep golden, fragile perfection with hollow blistered pockets.
• Thickness & Purpose: Focaccia is typically thicker (approx. 2 to 3.5 cm / 0.8–1.4 in) and enjoyed as an airy side or table bread. Schiacciata comes in two iconic styles: the thin, crunchy Classica (approx. 1.5 cm / 0.6 in) or the slightly taller Ripiena (approx. 2.2 cm / 0.9 in), engineered specifically to be split open for legendary Florentine panini (like All'Antico Vinaio).

For high-hydration doughs (75% to 85% water), traditional countertop kneading is nearly impossible because the dough is soft and wet. Instead of heavy kneading, artisan bakers use a folding schedule (stretch & folds or coil folds). This serves four critical biochemical purposes:

• 1. Building a strong gluten matrix without friction heat: Lifting and folding the dough every 20 minutes with wet hands aligns gluten proteins (glutenin and gliadin) into strong, parallel strands. Within 60 minutes, a sloppy dough transforms into a smooth, elastic dome without overheating in a mixer.
• 2. The 20-minute gluten relaxation cycle: Gluten bonds need rest to relax. After 20 minutes, tension subsides so you can stretch the dough further without tearing. Three rounds of 20 minutes (60 minutes total) are the proven sweet spot between structural integrity and an easy kitchen schedule.
• 3. Trapping large gas pockets (alveoles & open crumb): Each fold incorporates delicate micro-layers of air. During cold fermentation, this elastic gluten trap captures expanding carbon dioxide (CO₂), yielding the cloud-like, open crumb characteristic of masterclass panbreads.
• 4. Fermentation start & automatic yeast compensation: Keeping the dough at room temperature for the first hour kickstarts yeast metabolism before cold refrigeration (4°C / 39°F) slows it down. Our calculators automatically factor this 60-minute window into the Q₁₀ fermentation kinetics, reducing yeast dosage proportionally to prevent over-fermentation in the fridge.

Each method imparts distinct physical properties and flavor profiles to the dough:

• Direct dough: All ingredients are mixed in a single stage. This is the most controllable, reliable, and straightforward method. Ideal for honing baking fundamentals and precise timing.
• Biga (stiff preferment, 45-50% water): Biga fermenteers cold and dry (typically 16-24 hours at 16-18°C or partially in the fridge). It produces exceptional dough elasticity, a dramatic honeycomb alveolation in the rim (cornicione), complex lactic acidity, and maximum crunch. Baker's recommendation: use 40% to 60% biga for optimal balance.
• Poolish (liquid preferment, 100% water): Poolish ferments quickly and wet with equal parts flour and water and a tiny yeast dose. This yields high protease activity, producing a silky, pliable dough that stretches effortlessly with zero tear, accompanied by a tender crumb and crisp outer crust.

In the Pizza Calculator, you can switch between Direct, Biga, and Poolish with a single click. The mathematical core automatically computes exact flour, water, and yeast splits for both preferment and final dough, including cold yeast boosters!

This is known as the 100% biga trap. Many bakers assume: "If a 50% biga makes great pizza, 100% biga must be twice as good."

However, with 100% biga, all the flour has already been pre-digested by yeast and enzymes during phase one. When you mix the final dough in step two, there is no fresh flour left to nourish the fermentation or build new gluten bonds. The dough has zero reserve strength and must be baked within 2 to 3 hours before structural collapse sets in. Our calculator recommends 40% to 60% biga for consistent, stable, and forgiving dough handling.

When a biga is retrieved from the cold fridge (4°C / 39°F), the yeast cells are slumbering. Mixing this chilled mass with fresh flour and cold water can cause fermentation to stall for hours at room temperature.

The Pizzaformule.nl calculation engine resolves this automatically: the total calculated yeast is split into a base dosage for the biga (for flavor development) and a small booster for the main dough. This booster immediately ignites the fresh flour in step two, ensuring your proofing schedule completes exactly on time. Practical Step 2 tip: always dissolve this booster yeast first in a small splash of your weighed Step 2 water before adding it to the bowl; this guarantees that the micro-dose of yeast distributes 100% evenly through the firm preferment and fresh flour.

This is due to thermal inertia (delayed thermal conductivity) in dense dough masses. Kneading generates substantial friction heat, easily raising the finished dough temperature to 23°C–25°C (73°F–77°F).

When a warm dough ball is placed directly in the refrigerator, only the outer surface cools quickly. The core takes 4 to 6 hours to drop below 10°C (50°F). During those hours, yeast and enzyme kinetics in the core continue at full throttle, causing uncontrollable overproofing and gas ballooning in the fridge.

By adding ice-cold water (3°C to 5°C / 37°F to 41°F straight from the fridge) in step 2, you neutralize friction heat so the dough finishes kneading around 18°C (64°F). The core quickly chills to 4°C, ensuring a calm, safe, and controlled cold fermentation.

Short answer: preferably not for a full 24 hours. A classical 50% hydration Biga ripens optimally at 16°C to 18°C (61°F to 64°F) (wine cellar, cool pantry, or wine fridge).

Under the biological Q10 rule, enzyme and yeast activity is 40% to 50% faster at 21°C (70°F) than at 16°C (61°F). At 20°C–21°C, a Biga peaks after only 12 to 16 hours. Beyond that peak, three severe issues occur:

• Excess Acidity: Acetic acid accumulates rapidly, giving a sharp, unpleasantly sour flavor.
• Gluten Breakdown: Proteolytic enzymes digest the gluten strands early in the preferment, yielding a limp, tear-prone final dough.
• Sugar Depletion: The yeast consumes all fermentable sugars, leaving the pizza pale and unable to brown in the oven.

Solution: If you must ferment at 20°C–21°C (68°F–70°F), reduce the time to 12–16 hours or decrease the yeast percentage using our calculator. If 24 hours is essential to your schedule, find a cooler resting spot (15°C–17°C / 59°F–63°F) or move the Biga to the refrigerator after a brief 1-hour start.

Even with ingredients measured to a tenth of a gram and proofing schedules followed to the minute, home kitchen environments introduce dynamic variables. Baking is applied biochemistry and thermodynamics. Here are the 6 most common real-world culprits and how to prevent them:

Yes, pizza dough freezes remarkably well if you account for yeast kinetics. Freezing temperatures put yeast cells into dormancy, but ice crystals can rupture cell membranes if frozen after long proofing. With the right technique, frozen dough retains nearly 100% of its baking quality for up to 2 to 3 months.

For beginner bakers, a hydration of 60% to 62% is the optimal sweet spot between easy handling and authentic crust texture. At 60–62% water relative to flour weight, the gluten network develops rapidly, the dough will not stick unmanageably to your hands or work surface, and the dough ball maintains firm surface tension during fermentation.

Social media often glorifies extreme hydrations of 70% to 80% as the only way to bake artisan pizza. In reality, wet dough demands strong professional flour (W300+), specialized folding techniques (such as coil folds), and practiced dexterity when loading onto a peel. For beginners, excessive hydration frequently results in torn dough or pizzas glued to the peel. Start comfortably at 60% and gradually increase water by 2% per baking session as your feel for the dough matures.

When a dough ball snaps back like an elastic band as you try to stretch it into a pizza base, the gluten matrix is under excessive mechanical tension and lacks extensibility (relaxation). In 95% of cases, this has two distinct causes:

• The dough is still too cold: Gluten proteins and natural lipids are rigid at refrigerator temperatures (4°C / 39°F). Always allow dough balls to relax covered at room temperature (20–22°C / 68–72°F) for at least 2 to 3 hours before stretching.
• Insufficient rest after balling: Shaping balls pulls the gluten strands taut. After balling, the dough requires at least 2 to 4 hours of resting time (the appretto stage) so the tension can fully dissipate.
