HIBISCUS PETALS are edible flower petals, and have a lovely deep pinkish red colour.
Hibiscus flowers are most commonly used in tea and it's what gives the "zing" to Red Zinger Tea. It has a fresh, tart flavour that can be sweetened if desired. Hibiscus can be brewed and consumed hot, for a warming, comforting tea, or made into a pleasantly refreshing iced tea (a staple of Mexican cuisine known as agua de jamaica).
It can be infused into sugar. They can also be used to make tea, or in vegan tacos.
