Score and bake again

  3. Punch four rows of holes, four holes per row, into the dough (a fork works nicely).

  4. Flip the crackers and return to the oven for another half hour.

What each ingredient does

Flour
Forms the gluten network that gives the dough its firm, sturdy structure.
Water
Hydrates the flour so it binds into a cohesive dough.

The step that matters

Punching the holes before the second bake. The holes let steam escape during baking, so the crackers dry evenly and do not puff or crack unevenly. Skipping them can leave bubbles and a texture that varies across each piece.
