Fine sea salt
sale finoThe salt that seasons the dough itself — measured by weight, it controls both flavor and fermentation.

Quick answer
Fine sea salt dissolves evenly into focaccia dough and seasons it throughout. Use about 2% of the flour weight (roughly 20 g per 1000 g flour). Weigh it — salts vary enormously by volume — and keep it from landing directly on the yeast while mixing.
What it contributes
Salt does far more than make focaccia taste salty. It sharpens and balances every other flavor, so an under-salted focaccia tastes flat and doughy no matter how well it was fermented. It also strengthens the gluten network slightly and, importantly, slows and steadies fermentation — salt tempers the yeast so the dough rises at a controlled pace and develops flavor.
Fine sea salt is the workhorse for the dough because it dissolves quickly and distributes evenly, unlike coarse crystals that can leave salty pockets.
How much to use
The standard is about 2% of the flour weight — 20 g of salt per 1000 g of flour. Below roughly 1.8% the bread starts to taste bland; much above 2.2% it tastes salty and fermentation drags. Two percent is a reliable default you can nudge to taste.
This is a baker’s-percentage figure, which is why weighing matters: measuring by teaspoon is unreliable because different salts have wildly different densities.
Salt type changes the volume
By weight, pure salt is pure salt — but by volume, a teaspoon of fine sea salt, fine table salt, and coarse kosher salt can differ by nearly a factor of two because of crystal size. A recipe that says "1 teaspoon salt" is ambiguous; the same teaspoon of flaky kosher salt weighs far less than fine table salt, so following it blindly can leave you badly under-salted.
The fix is to weigh in grams and target roughly 2% of the flour. If you must use volume, know which salt the recipe assumed.
Handling and storage
Keep salt away from direct contact with yeast in a dry bowl — concentrated salt draws water out of yeast cells and can weaken them. Mix salt into the flour on the opposite side from the yeast, or dissolve one of them in the water first. Salt itself keeps essentially forever in a dry, sealed container; only anti-caking additives or dampness cause clumping.
Where to buy it
Any fine sea salt or fine non-iodized salt works for the dough. Iodized table salt is usable but some bakers find it faintly metallic; plain fine sea salt is the safe default. Buy the finishing (flaky) salt separately.

Frequently asked
- How much salt should focaccia dough have?
- About 2% of the flour weight — roughly 20 g per 1000 g flour. Under about 1.8% tastes bland; over 2.2% tastes salty and slows fermentation.
- Does the type of salt matter?
- By weight, no — by volume, very much. Crystal size makes a teaspoon of one salt weigh nearly twice another. Weigh salt in grams rather than measuring by spoon.
- Why should salt not touch the yeast directly?
- Concentrated salt draws water out of yeast cells and can weaken them. Keep them apart in a dry bowl, or dissolve one in the water first.
