Start by boiling 2 cups of water in a small saucepan. Once the water is hot, add 1 tablespoon of butterfly pea flowers, allowing them to steep for about 10 minutes until the water transforms into a rich, deep blue hue. Afterward, strain the flowers, keeping the beautiful blue brew aside to cool.

In a large pitcher, mix the cooled butterfly pea flower brew with 2 cups of cold water. Add your choice of natural sweetener, adjusting the amount according to your preferred sweetness level. Stir gently for about 30 seconds until the sweetener dissolves completely.

Fill clear glasses with ice cubes to enhance the visual appeal. Pour the blue lemonade mixture over the ice.

Squeeze the juice of half a lemon into each glass of blue lemonade, watching as the color changes from blue to a delightful purple.

For an extra touch of elegance, add slices of fresh citrus fruits or a sprig of mint to each glass.
