What Causes Flaky Pie Crust?
There are various reasons why a pie crust may turn flaky. One of the primary reasons is overworking the dough, either by kneading it too much or rolling it out multiple times. This causes the fat in the crust to melt, resulting in a tough and crumbly texture. Another reason could be the type of fat used in the crust, as harder fats like butter or shortening tend to produce a flakier crust than softer fats like margarine. The use of too much flour or not enough water in the dough can also make the crust dry and flaky. Lastly, overbaking the crust can cause it to become excessively dry and brittle.
