FOR THE SORREL BASE:
4 cups water
1 (2-inch) nub fresh ginger, peeled and sliced
2 tablespoons Frontier Co-op powdered sheep sorrel
1/4 teaspoon ground Frontier Co-op ground cloves
1/4 teaspoon ground cinnamon
FOR THE COCKTAIL:
3 ounces sorrel base
1/2 fluid ounce fresh lime juice
1 fluid ounce simple syrup
1/2 fluid ounce rum
1) Bring the ingredients for the sorrel base to a full boil. Remove from heat and cover. Allow mixture to sit for 2 hours.
2) Using a coffee pour-over, strain the sorrel mixture through a coffee filter into a large jar. Refrigerate until chilled.
3) Fill a shaker with ice and add ingredients for one cocktail. Shake well and pour into a glass and serve (Note you can adjust the amount of simple syrup, rum, and lime juice to taste).
Make this cocktail without refined sugar by using a liquid natural sweetener such as pure maple syrup or coconut palm nectar.
The sorrel base can be made ahead of time and kept it in a sealed jar in the refrigerator for up to 10 days.
