Storage Tips
This lemonade is best enjoyed fresh to preserve its vibrant color. If you need to make it in advance prepare the butterfly pea flower tea and lemonade base separately and chill them. Assemble the drinks just before serving for the magic effect. If the lemonade sits too long after mixing the color may dull and the ice can dilute the flavor.
Ingredient Substitutions
You can use honey or agave syrup in place of granulated sugar for a different sweetness profile. If you want a bubbly version try replacing the cold water in the lemonade with sparkling water. For a more herbal finish add a few bruised basil or Thai basil leaves to the garnish.
Serving Suggestions
Serve in tall clear glasses for full effect. Add extra slices of lemon or even edible flowers for an extra wow factor. This recipe is perfect for picnics birthdays baby showers or anywhere you want something both pretty and refreshing.
