You can find dried hibiscus flowers and rosewater at specialty food stores. Hibiscus is high in vitamin C and makes a great tea if you find yourself wondering what to do with any leftovers. Simply pour a cup of boiling water over approx 1 teaspoon dried flowers and steep for five minutes before drinking. Add a touch of honey or sugar to sweeten if desired. I find you can get two brews from the flowers before they’re destined for the compost.
