Focaccia Hydration Percentage: How to Dimple a Wet Dough
Focaccia dough feels impossible on purpose. At 80% hydration it sticks, slumps, and refuses to be a ball. The pan is why that is allowed. A loaf has to hold a shape in the air. Focaccia has to fill a rectangle. The tin does the structural job the gluten is too wet to do alone.
Sixty percent is sheet-pan pizza. Seventy is a steel pie. Focaccia lives higher, usually 75–85%, because the crumb you want is open and the bake is long enough to set it. The pan forgives the slack. Your hands do not have to.
Why it feels wrong
High hydration means the gluten network is diluted. The dough tears if you treat it like bread. It also flows. Flow is the feature. You are not building a freestanding boule. You are building a sheet that will be fried on the bottom by oil and set by an oven that has time.
Strength still matters. A weak 80% dough makes a dense, oily cushion. A developed 80% dough makes holes you can see. Development comes from folds, not from kneading it into a smooth ball it will never be.
Oil is not a garnish here. Oil in the pan is a structural ingredient. It fries the underside, stops the dough welding to the metal, and sits in the dimples so the top crisps instead of drying. A dry pan bakes a flatbread. An oiled pan bakes focaccia.
Coil folds, in the pan
Do the strength work where the dough already lives. Oil the pan. Tip the dough in. Wet or oiled hands.
A coil fold in the pan: lift one side, stretch it up until it resists, and fold it over the middle. Turn the pan. Repeat. Three or four turns is a set. The dough will not look tidy. It will look thicker than it did.
Rest. Repeat the set two or three times across the first hour or two. You are building layers and elasticity without ever picking the mass up onto a bare bench, where an 80% dough becomes a cleanup project.
Stop folding when the dough holds a lobe for a moment before it relaxes. That is enough gluten. More folds just degas it.
Yeast still follows the clock, not the pan. An 8-hour room ferment wants about 0.30% instant yeast. A 24-hour cold ferment wants about 0.10%. The pizza engine doses from the schedule you actually have. Set the hydration you mean. Let it return the grams.
How to dimple
Dimple late. The dough should be relaxed, jiggly, and already filling most of the pan. If it snaps back and leaves the corners empty, it is early. Wait.
Oil your fingers. Not flour. Flour fights the hydration you paid for.
Drive straight down, to the pan, and pull out. Do not drag. Dragging rips the sheet and smears the gas out of it. Spacing is a finger-width or two. Cover the surface. You are parking oil in pockets, not painting a pattern.
The dough should fill back slowly around the finger marks, not seal them shut and not collapse to the metal. Seals shut: under-proofed, or you were too gentle to reach the pan. Collapses and will not refill the corners: over-proofed. Bake that one. Do not dimple it again.
A second, lighter dimple after a short rest is enough if the first set swelled shut. A third pass is how you knock the crumb out.
Bake it like a pan, not a pie
Heat from below is the point. A loaded pan on a hot stone or steel, or a thorough preheat if the pan goes in alone. The oil does the browning on the bottom. The dimples do it on top.
Salt goes on at the dimple, not only in the dough. Flake salt in the oil pockets stays put. Herbs go on then too, so they fry instead of burn.
If the underside is pale, the pan was cold or the rack was too high. If the crumb is gummy under a dark top, the hydration was fine and the bake was short. Give it longer at a slightly lower rack. Do not “fix” gummy focaccia by lowering the water next time. Fix the bake.
Size the batch from the pan, not from a loaf formula.
