Heat water in a tea kettle over high heat. Alternately, if you are doing 2 cups or a larger amount then you can boil the water in a pot and steep the tea right in the pot.
Add 1/4 cup Blue Butterfly Pea Flower Tea flowers into a mesh tea ball and add to a large mug (if 1 serving) or 4-cup heat-safe wet measure (if making for 2).
Pour the hot water over the tea ball and allow to steep for 3-8 minutes, depending on how dark you want the tea. (Do not steep for longer than 10 minutes to avoid the tea from becoming bitter.).
