What a great idea!!
I found out this works well years ago. Pumpkin pie was the all time favorite in my family and that’s what they would always ask for.
A friend at work grew huge pumpkins, and he would give me one every year. I’d use it to make pumpkin filling and then freeze the filling in pie pans. If you don’t have lots of pie pans and you have lots of filling - you just freeze, release and freeze some more.
Worked for me.
