Just be sure to juice your fruit first. We recommend chopping or crushing your fruit up, and then freezing it to break down the cell walls and better extract the flavor.
Then, simmer your fruit with water in a large pot for 20 minutes to extract the flavor. Add your sugar (or honey, if you want!) according to the drink designer.
Let your juice cool, then strain it. Try to remove as much of the fruit's crush as possible. Then, pour it into your jug and add your brewsy bag.
