Ingredients

2 cups sugar

1/2 cup coriander seeds, toasted and coarsely ground

Zest of 2 oranges, removed in strips with a vegetable peeler

8 cups fresh orange juice (from about 20 oranges)

1/2 cup fresh lemon juice (from 3 or 4 lemons)

Ice

Preparation

Bring sugar and 2 cups water to a boil in a small pot. Reduce heat; simmer, stirring, until sugar dissolves. Remove from heat; stir in coriander and orange zest. Cover, and let steep 2 hours. Simple syrup can be refrigerated up to 2 weeks. Strain before using.

Combine syrup and juices in a 3-quart pitcher, and refrigerate until cold, at least 2 hours and up to 2 days. Serve over ice.
