How do French cakes and pastries use basic dough types?

French baking relies on specific dough types, each engineered through technique and ingredient ratios to achieve distinct textures:

• Pâte Feuilletée (Puff Pastry): This dough is created by folding and refolding layers of fat into the dough, resulting in hundreds of thin strata. During baking, the steam trapped between these layers causes the pastry to expand significantly, creating a light, crisp, and flaky texture used for items like napoleons and patty shells.123
• Pâte à Choux: A very light, egg-based dough that is cooked before baking. It is the foundation for classic French pastries such as cream puffs and éclairs.45
• Pâte Brisée: Often translated as "broken pastry," this is a rich, tender dough commonly used for tart shells. It is handled to ensure the fat is well-amalgamated, resulting in a fine-textured, crumbly finish rather than a flaky one.61

These doughs demonstrate the French mastery of manipulating flour, fat, and leavening to create a wide variety of culinary textures.12
