Add a squeeze of lemon for brightness. Stir in honey or maple syrup to tame the fire. Feeling fancy? Throw in a cinnamon stick or a few mint leaves while it simmers.
Want it cold? Boil a big batch, let it cool, and store it in the fridge. Pour it over ice for a zingy iced tea that beats any store-bought soda. It’s also amazing as a base for smoothies or cocktails.
