Agua de Jamaica (aka Hibiscus tea) is an infusion of dried hibiscus flowers. Popular at Mexican taquerias, this agua fresca is loaded with Vitamin C and can even lower blood pressure!
1 Boil water with sugar and spices: Put 4 cups of the water and the sugar in a medium saucepan. Add cinnamon, ginger slices, and/or a few allspice berries if you would like. Heat until boiling and the sugar has dissolved.
2 Steep with dried hibiscus flowers: Remove from heat. Stir in the dried hibiscus flowers. Cover and let sit for 20 minutes.
3 Strain: Strain into a pitcher and discard the used hibiscus flowers, ginger, cinnamon, and/or allspice berries.
(At this point you can store ahead the concentrate, chilled, until ready to make the drink.)
4 Add water: Add remaining 4 cups of water (or if you want to chill the drink quickly, ice and water) to the concentrate, and chill.
Alternatively you can add ice and chilled soda water for a bubbly version.
Add a little lime juice for a more punch-like flavor.
Serve over ice with a slice of orange or lime.
