Can use baking powder instead of flour when making a pie?

Here's why:

* Structure: Flour provides the structure for the pie crust. It forms a gluten network that holds the crust together, preventing it from collapsing. Baking powder is a leavening agent, responsible for making things rise, but it doesn't offer the structural support needed for a pie crust.

* Texture: Flour creates the texture of the pie crust, whether it's flaky, tender, or chewy. Baking powder would make the crust airy and spongy, not the desired texture for a pie.

* Flavor: Flour provides a subtle taste to the pie crust. Baking powder has a distinct flavor that would be overwhelming in a pie crust.

While you can't replace flour with baking powder, you can use a combination of flour and baking powder in some pie crust recipes. This is often done to achieve a more tender and flaky crust.

However, if you're looking to replace flour entirely, you'll need to use an alternative like almond flour, coconut flour, or oat flour. These alternatives will require adjustments to the recipe to ensure the correct consistency and texture.
