- 2 cups sugar
- 2 cups water
- 5 1/3 cups fresh or frozen cranberries (not thawed; 24 oz)
- 1/4 cup vodka
- 1/4 cup fresh lime juice
- 2 tablespoons Cointreau or other orange liqueur
- Special equipment: an ice cream maker
- Bring sugar and water to a boil in a 3-quart heavy saucepan, stirring until sugar is dissolved. Add cranberries and simmer, uncovered, until berries are collapsed, 8 to 10 minutes. Pour through a large sieve into a bowl, gently pressing on solids to extract liquid (without forcing pulp through), and discard solids. Cool syrup, then chill, covered, until cold.
- Stir in vodka, lime juice, and Cointreau and freeze in ice cream maker. Transfer to an airtight container and put in freezer to harden.
