What is the ratio in the 3-2-1 Dough formula for pie crust?

• A. 2 parts flour, 3 parts fat, 1 part liquid
• B. 3 parts flour, 2 parts fat, 1 part liquid
• C. 1 part flour, 3 parts fat, 2 parts liquid
• D. 3 parts fat, 1 part flour, 2 parts liquid

Answer: (B)

The 3-2-1 dough formula for pie crust is structured as follows: for every three parts of flour, you use two parts of fat (which could be butter, shortening, or lard), and one part of liquid (typically water). This ratio is designed to create a flaky and tender texture in the crust.

Flour provides the structure and necessary gluten in the dough, while the fat contributes to both flavor and flakiness by coating the flour particles, preventing them from fully absorbing water and creating an undesirable toughness. The liquid is added to bring the dough together without overworking it, maintaining its desired texture.

In this formula, three parts flour is the highest ratio, establishing the foundation of the crust. Using two parts fat ensures richness and enhances the mouthfeel, while one part liquid balances the mixture, resulting in a dough that is manageable to roll out but still sufficiently tender once baked. This balance is essential in achieving a desirable pie crust that remains crisp and holds its shape during baking.
