Dried hibiscus flowers (Hibiscus sabdariffa) is much used in Mexico and the Carribean, dried and infused to make drinks, sometimes rehydrated and cooked with other ingredients. In the United States, dried hibiscus flowers are used to brew a refreshing, intensely flavored, deep ruby red tea. Hibiscus tea is a favorite beverage south of the border where it is known as flor de Jamaica.
In Costa Rica and Central America, the sweetened hibiscus drink is fermented into a mildly alcoholic beverage that looks like red wine.
Dried hibiscus flowers are remarkable for being a concentrated source of Vitamin C, antioxidants, and gel-forming pectin.
