Baking Powder (Best Option)
1 1/2 teaspoons per 2 cups of flourBaking powder is a chemical leavening agent that releases carbon dioxide gas when moistened and heated, causing the dough to rise. It works well in quick breads and pie crusts where a tender, flaky texture is desired without the need for yeast fermentation.
To ensure optimal rise and texture, mix baking powder thoroughly with the flour before adding liquids. Avoid overmixing the dough to prevent toughness. Baking powder acts immediately, so bake the dough soon after preparation.
Compared to yeast, baking powder yields a crust that is less chewy and lacks the subtle fermented flavor, but it excels in convenience and produces a reliably tender and flaky crust suitable for chicken pot pie.
