Ingredients
1/2 cup pink or red grapefruit juice (from about 1 small grapefruit)
1/2 cup pomegranate juice (from about 1 medium pomegranate)
1 cup sugar
2 star anise pods
Ice
Soda water
Pomegranate arils for garnish (optional)
Directions
Combine grapefruit juice, pomegranate juice, sugar, and star anise in a small saucepan over medium heat. Boil for 1 minute, stirring constantly to dissolve the sugars.
Remove from heat and let sit 30 minutes. Strain and discard solids. Let syrup cool completely.
To serve, fill an 8-ounce glass halfway with ice cubes, add 3 tablespoons of syrup, fill with soda water, and stir. Add more syrup for a sweeter or stronger flavor. Garnish with pomegranate arils.
