Hi there!
That pie sounds delicious! If you're looking for a thick, soft, non-flaky crust, you might want to try a pâte brisée or a pie crust that incorporates sour cream or yogurt, which can give the dough a softer, more tender texture. You could also experiment with using more butter or shortening in the dough, which can help achieve that soft consistency. Another tip is to avoid overworking the dough and to bake it at a slightly lower temperature to keep it from getting too crispy. If you can, try adding a bit of baking powder to the
crust recipe, which can also help with softness.
Hopefully, these tips help you recreate that delicious pie crust at home!
