The ultimate focaccia dough: hydration, pan sizing and the magic of salamoia
Published by Pizzaformule.nl Editorial • Reading time: approx. 7 minutes
Nothing quite matches the sight and aroma of freshly baked focaccia sliding out of the oven: a shimmering, golden-brown crust dotted with deep craters, sizzling from rich olive oil on the bottom, and internally so tender and airy that it practically melts on the palate.
Yet many home bakers mistakenly view focaccia as merely a 'thick pizza base'. In reality, pan bread is an art form in its own right. While traditional Neapolitan pizza bakes directly on a 450°C (850°F) stone, focaccia relies entirely on the structural support of a baking pan. Those vertical rim walls change the physics: they allow the dough to carry an extraordinary hydration of 75% to 85% without spreading flat.
In this guide, we dive into the science and craft of authentic focaccia: from custom pan thickness factors to hands-free coil folds and the indispensable secret of Italian salamoia brine.
The three styles: Genovese, Alta or Sandwich?
The ratio between pan floor surface and dough weight dictates the height and texture of your crumb.
Classic Genovese
The archetypal Ligurian focaccia. Rich with extra virgin olive oil, crisp, golden and approximately 1.5 to 2 cm high.
- • Thickness factor: 0.60 g/cm²
- • Height: ~1.5 – 2 cm (0.6 - 0.8 in)
- • Character: Crispy crust, deep dimples
Aperitivo with wine, dipped into aged balsamic vinegar and fruity olive oil.
Focaccia Alta
Traditional high pan focaccia. Packed with irregular air pockets and a velvety, cloud-like open crumb.
- • Thickness factor: 0.75 g/cm²
- • Height: ~2.5 cm (1.0 in)
- • Character: Pillow-soft interior, golden crust
Serving alongside pasta or soups, topped with fresh rosemary and sea salt flakes.
Sandwich / Extra Tall
Inspired by legendary Florentine sandwich bars (All'Antico Vinaio). Maximum vertical oven spring with sturdy gluten strands.
- • Thickness factor: 0.95 g/cm²
- • Height: ~3.5 – 4 cm (1.4 - 1.6 in)
- • Character: Exceptional volume, ideal for slicing horizontally
Stuffed paninis with mortadella, creamy stracciatella, pistachio pesto or prosciutto.
The three layers: the secret to an unctuous crumb and crisp crust
Many bakers casually drizzle olive oil over dough right before baking. A master focaccia relies on three distinct functional layers:
Extra virgin olive oil adsorbs at gas-liquid interfaces in the gluten network, stabilizing gas cells during oven spring and retarding starch retrogradation so the crumb stays tender for days (Pareyt et al., 2011).
A generous pool of oil (at least 10–15 grams per pan) prevents sticking and shallow-fries the bottom crust via rapid thermal conduction to golden crisp perfection (Delcuratolo et al., 2008).
The defining Italian secret: a vigorously whisked emulsion of lukewarm water, oil and sea salt poured over the dough right before dimpling. Evaporating water delays premature crust setting before Maillard browning begins (Purlis, 2010).
Baker's math: calculate exact dough weight for any pan
No more guesswork: scale any recipe flawlessly to your specific sheet pan or skillet.
| Pan Size | Surface Area | Genovese (0.60) | Alta (0.75) | Sandwich (0.95) |
|---|---|---|---|---|
| 25 × 25 cm (Square) | 625 cm² | 375 g | 469 g | 594 g |
| 30 × 20 cm (Small sheet) | 600 cm² | 360 g | 450 g | 570 g |
| 40 × 30 cm (Standard sheet) | 1,200 cm² | 720 g | 900 g | 1,140 g |
| Ø 28 cm (Round pan/skillet) | 615 cm² | 369 g | 461 g | 584 g |
Kneading technique: autolyse and coil folds
Because genuine focaccia dough contains 78% to 82% water, kneading on a tabletop produces sticky chaos. Professional bakers rely on two clean techniques:
- Autolyse (Flour rest): Mix flour with ~90% water until fully hydrated, then let it rest covered for 20–30 minutes. Spontaneous hydrogen bonding initiates gluten network formation without mechanical stress (Belton, 1999).
- Coil Folds: After incorporating salt, yeast and oil, lift the dough with wet hands from the center and tuck the ends underneath. Rotate the bowl 90 degrees and repeat. Perform 2 to 3 sets spaced 20 minutes apart. This biaxial strain hardening aligns the gluten network into a silky, elastic balloon with superior gas retention (Dobraszczyk & Morgenstern, 2003).
Baking at 230°C (450°F): why focaccia avoids pizza heat
Unlike a 3-millimeter Neapolitan pizza, focaccia holds substantial dough depth. In a scorching 450°C (850°F) oven, surface olive oil and brine burn within minutes while the core remains gummy and raw.
A standard home oven set to 215°C – 230°C (420°F – 450°F) conventional or 195°C – 210°C (385°F – 410°F) fan provides the ideal thermal balance. In 18 to 24 minutes, the crumb reaches an optimal internal doneness of 94°C – 96°C (201°F – 205°F) for complete starch gelatinization and protein coagulation (Cauvain & Young, 2015) while the bottom crust crisps deeply in oil.
