- 1/2 cup crème de cassis (black-currant liqueur)
 - 1/4 cup plus 1 tablespoon sugar, divided
 - 2 teaspoon fresh lemon juice, or to taste
 - 4 cups mixed berries (1 1/4 pounds), halved or quartered if large
 - 3/4 cup chilled heavy cream
 - 1 pint vanilla ice cream
 - 1 pint raspberry sorbet
 
- Bring crème de cassis and 1/4 cup sugar to a simmer, stirring until sugar has dissolved (if alcohol flames, momentarily cover with lid to extinguish). Stir in lemon juice.
 - Pour syrup over berries, stirring gently to coat. Let stand 10 minutes.
 - Beat cream with remaining tablespoon sugar using an electric mixer until it just holds stiff peaks.
 - Divide ice cream and sorbet among glasses. Top with berries and syrup, then with whipped cream.
