Try wild blueberries, or if cultivated berries are your only choice, use fruit juice instead of water for additional flavor.
Combine berries, water or juice, sugar, lemon, cinnamon, and wine in saucepan. Bring just to a boil, reduce heat and simmer 25 minutes, partially covered. Remove lemon slices and cinnamon stick and press mixture through food mill. Cool and chill. Add cream and stir until smooth. Garnish with additional sour cream or whipped cream.
