Test the Gluten Structure. Use a piece of dough the size of a Tablespoon. This dough is sticky but don’t add flour to it. Roll it between your palms, not your fingers. Keep your fingers open. Air flow keeps the dough from sticking.
Drop the dough ball into bench flour. Roll it around to coat the outside.
Flatten it with the heel of your hand. Use quick and light gestures, up and down.
The dough windowpanes quickly because of the Autolyse. Flour your fingers. Use the pads of your fingers (not your fingernails) to stretch the dough. The dough is slack and sticky, so don’t overstretch it. A bit of elasticity is all you need to see.
