White Nectarine Sorbet

Ingredients

• About 1 1/2 pounds ripe white nectarines, chilled
• 3 tablespoons lemon juice
• 2 to 3 tablespoons sugar
• 1 tablespoon orange-flavor liqueur (optional)
• 1/4 teaspoon vanilla
• 1/4 cup sour cream or crème fraîche

Preparation

1. 1. Slice nectarines into a bowl. Add lemon juice and mix with fruit to keep slices from darkening.
2. 2. Pour fruit and juice into a blender or food processor. Add 2 tablespoons sugar, liqueur, vanilla, and sour cream. Whirl until peel is finely ground (it turns the purée pink). Taste and add more sugar if desired.
3. 3. Pour nectarine mixture into a 1-quart or larger ice cream maker (refrigerated or frozen-cylinder kind, or one that uses salt and ice) and follow manufacturer's directions. Churn until dasher is very hard to turn.
4. 4. Scoop nectarine sorbet into bowls and serve.
