I've been making apple pie filling for almost 25 years. 1 quart works great for pie. Just make like you're using the canned apple or cherry pie filling from the store. I just made apple crisp last night using canned apples. I use 1 qt for a 8-9 inch square pan or 2 quarts for a 9x13 pan. I use any crisp topping that I want for the topping. My family prefers my gma's crisp topping using flour, brown sugar, oatmeal and butter.
