My mom found this recipe years ago and it has become a favorite.
3/4 cup water
1/3 cup sugar
1 can cherry pie filling
2 3oz boxes cherry Jello or 1 large box of Jello
1 can crushed pineapple
1 cup cold cherry coke or cherry pepsi
Combine water and sugar and bring to a boil. Add pie filling and return to a boil. Pour boiling mixture over gelatin, stir to dissolve. Add pineapple with juice and cola. Place in a 9x13 or glass bowl and chill.
