Begin by preparing your ingredients. Cut the honeydew melon into cubes and add them to your blender along with the freshly squeezed lime juice, lime zest, and mint leaves. Blend on medium-high for about 2 minutes until smooth.

Next, grab a fine mesh sieve to strain the blended mixture. Place it over a bowl, pour through to separate the concentrate from pulp.

Transfer the smooth concentrate into a jar or airtight container. Seal it tightly and refrigerate until ready to serve.

To serve, combine the chilled concentrate with sparkling water or club soda in a glass just before serving.
