Rinse the teapot with boiling water, put all ingredients except sugar. I brewed in different ways: just with hibiscus, hibiscus+black tea and just black tea. I liked it better: hibiscus + black tea. Try, experiment to your taste.
Pour boiling water and insist at least 10 minutes, I usually insist 20 minutes, for saturation.
If you brew in an ordinary teapot (like me), then before use, you need to slightly press down the welding (I used a pusher), so that the fruits give more juice. To brew this tea will be more convenient French press, but I do not have it. Strain the tea leaves, add sugar to taste and you can enjoy the magical taste and aroma.
