Start by peeling and chopping one large dragonfruit into smaller pieces. Place them in a blender with ¼ cup of warm water and blend until smooth.

In a small saucepan, combine ½ to ¾ cup of granulated sugar with 1 cup of water. Heat gently, stirring frequently until the sugar dissolves, about 3-5 minutes.

Juice 6 to 8 fresh lemons to yield about 1 cup of juice. Combine this juice with 4 cups of cold water in a large pitcher.

Strain the blended dragonfruit puree into the pitcher using a fine-mesh strainer to ensure a smooth texture.

Stir to combine all ingredients, cover, and chill in the refrigerator for at least 2 hours.

Serve over ice, garnishing with lemon slices, mint leaves, or dragonfruit cubes as desired.
