We love the combination of citrusy hibiscus, spicy fresh ginger, and aromatic cloves in this DIY cocktail syrup. It makes an excellent holiday gift, but be sure to save a bottle for yourself to make our Hibiscus Margarita.
Combine sugar, cloves, ginger, and 4 cups water in a medium saucepan. Bring to a simmer over medium-high, stirring until sugar is dissolved (if it begins to boil, reduce heat -- boiling will make the syrup cloudy). Remove from heat; let steep 10 minutes. Stir in hibiscus leaves; let steep another 35 minutes.
Strain through a fine-mesh sieve into a large liquid-measuring cup; discard solids. Refrigerate until completely cool, 1 hour. Pour into gift bottles. Syrup can be stored in bottles, refrigerated, up to 1 month.
