This is what I usually use:
Ground Cherry Apple Pie (Note: This recipe is for 2 pies)
Filling:
1 c. cold water
1 cup perma flo, clear gel, or cornstarch (I prefer perma flo)
3 c. water
3 1/2 c. sugar
1 tsp. salt
2 T. butter
6 c. ground cherries
4 big apples, chopped
Mix 1 c. water with perma...
DH loves ground cherry pie! They are sour so don't try to cut the sugar too much. If I mix them with apple in a pie, they don't require quite as much sugar, and DH still loves it.
