Peel and chop the ripe dragonfruit into small pieces, place in a blender with 4 cups of cold water, and blend on high for about 30 seconds until smooth.

Optionally strain the mixture through a fine mesh sieve into a large bowl or pitcher to remove pulp.

In a separate pitcher, squeeze lemons to make 2 cups of lemon juice, then stir in sweetener until dissolved.

Slowly mix the dragonfruit blend with the lemonade mixture and stir well for about 1 minute.

Taste the lemonade and adjust sweetness if needed by adding more sugar or honey.

Fill glasses with ice, pour the lemonade over, and garnish with fresh mint leaves.
