Poolish Croissant Dough

THE RECIPE Poolish croissant dough involves a few more steps than classic croissant dough; these steps are often used in bread baking to create a richer, more yeasty flavor. Fortunately, most modifications to the preparation simply involve increasing the various resting and rising times. During the additional poolish dough step, a portion of the dough is left to ferment before the rest.
