- 2 quarts blackberries, about 8 cups
- 1 cup sugar
- 1/4 cup cassis
- 6 sweet shortcakes, for serving
- Place in a large bowl and mix to dissolve the sugar. Place 6 cups of this mixture into a large baggie. Place the remaining mixture in the food processor, and pulse until it is a smooth puree. Pour the puree over the berries and seal the bag. Serve with shortcakes and sour cream madness.
