Here's a recipe for Blueberry Fool:
1 cup blueberries simmered in 1/3 cup water until tender (10 min)
Add 2 T sugar and 1T creme de cassis. Cool in pan then
chill for 1 to 2 hours.
Fold in 1 cup heavy cream whipped with 1 T sugar and 1/4 t lemon zest
Serve in chilled glasses.
I cheat and use vanilla yogurt instead of the whipped cream when I'm feeling health conscious.
