Ingredients

3 quarts (12 cups) water

1 (1/2-inch) piece ginger, finely grated

1 1/2 cups dried Jamaica flowers (also known as hibiscus or flor de Jamaica)

1 1/2 cups granulated sugar

2 tablespoons freshly squeezed lime juice (from about 1 large lime)

Preparation

Combine water and ginger in a large pot and bring to a boil over high heat. Remove from heat and stir in Jamaica flowers and sugar until sugar has dissolved. Let steep 10 minutes. Strain through a chinois or fine mesh strainer into a large, heat-resistant bowl or pot. Stir in lime juice and set aside to cool. Refrigerate until ready to use. Serve over ice.
