Add the hibiscus petals or teabags to a pitcher and pour the boiling water overtop. Let this steep for a few minutes before stirring in the honey until it dissolves.
Let the tea cool on the counter before removing the hibiscus or teabags - you want it to be very strong. Once it's cool, add the lime juice. Refrigerate until very cold, and serve with sliced lime, ice, and mint.
Juice of two limes, Lime slices and mint leaves for garnish
This keeps well in the fridge and even improves after a day or two.
Notes
1. Dried hibiscus petals can be purchased at Central American shops or in some supermarkets.2. You can, of course, substitute another sweetener for a vegan option. Maple syrup is good.
