Creme Fraiche Ice Cream With Torrent Of Berries

2 C. creme fraiche or sour cream, or 1 cup of each
2 C. buttermilk
1 t. vanilla extract
1 1/4 C. sugar
1 T. lemon juice

Berries:
2 (12-oz.) bags mixed frozen berries
1 pint homegrown strawberries, halved
2 T. cassis, black currant liqueur
sugar to taste
half-pint whipping cream, whipped

Combine all ice cream ingredients in a bowl and whip until smooth. Process in an ice-cream maker and then freeze until firm.

Thaw berries in refrigerator overnight. Push half of one bag through a sieve. Add the remaining berries to the pulp. Add cassis. Add sugar. The fruit should be fairly sweet -- the ice cream is tart. Garnish with whipped cream.

Serves 8 to 10.
