Ingredients

2/3 cup sugar

8 ounces fresh or frozen cranberries (2 cups)

1 blood orange, quartered and cut into 1/4-inch slices, plus more slices for serving

8 ounces vodka, chilled

1/4 cup fresh lime juice

16 ounces ginger beer, chilled

Crushed ice and fresh mint leaves, for serving

Preparation

Stir together sugar, cranberries, orange slices, and 1/2 cup water in a small saucepan. Cook over medium-high, stirring occasionally, until cranberries just start to burst, about 5 minutes. Remove from heat; let cool completely. Remove orange slices; discard. Refrigerate until cold, at least 1 hour and up to 1 week.

In a pitcher, combine syrup, vodka, lime juice, and ginger beer. Serve over crushed ice, with mint and fresh orange slices.
