Ingredients:
5 ounces fresh, or 1/2 ounce dried, hibiscus calyxes
1 small cinnamon stick
3 whole cloves
3 whole allspice berries
sugar, to taste
4 cups cold water
Directions:
If using fresh calyxes, prepare them by slicing in half lengthwise (through the stem), carefully popping out and discarding the green fruits, and reserving the calyx halves.
Combine the hibiscus and spices with 3 cups of water in a saucepan. Cover and bring to a boil. (Hibiscus tea must be boiled to bring out the red color and distinct flavor.)
Remove from heat and allow the mixture to steep for 10-15 minutes if using dried hibiscus and 20-30 minutes if using fresh.
Strain the mixture into a 1-quart jar or pitcher and stir in the desired amount of sweetener and the remaining cup of cold water.
Serve chilled.
