This easy 4-ingredient blueberry lemonade recipe from scratch couldn't get any easier! You can also use red or black grapes instead of blueberries. Cooking times will vary.
Wash the blueberries well, drain it and add sugar + 1 tablespoons lemon juice + 1 tablespoon lemon zest + 1 tablespoon of water to blueberries and place it on medium high heat. Once it starts bubbling, turn the heat to low and let it simmer for about 10 minutes.
Strain the syrup through a fine mesh. Let it cool completely before using.
Add 2 tablespoons of syrup to 1 cup of water, throw in some ice and mint leaves, reserved lemon juice and serve. (Taste and adjust the sweetness as needed by adding more syrup.) The color of the lemonade will also depend on how much syrup you add.
You can also store the syrup in an airtight jar in the refrigerator for couple of days.
