Cooks' notes:
This recipe makes more syrup than you'll need for 6 drinks. Use additional for extra cocktails or stir it into sparkling water or lemonade for delicious nonalcoholic drinks. Syrup keeps, covered and chilled, 3 days.

Yield
Serves 6
Ingredients
2 cups fresh blackberries
1/4 cup plus 2 tablespoons sugar

Preparation
Step 1
Simmer blackberries, sugar, water, and rosemary in a small heavy saucepan, uncovered, stirring occasionally, until thickened and reduced by about two thirds, about 20 minutes.
Step 2
Pour into a very fine sieve set over a glass measure and let stand 5 minutes (there will be about 1/3 cup). Discard solids (do not press on them). Chill syrup, covered, until cold.

Divide Prosecco among 6 small flutes, then pour 1 1/2 teaspoons syrup into each drink.
