In a blender, blend the watermelon chunks and blend until completely pureed and watery. Add the handful of mint leaves and blend until mint has disappeared. Taste with a spoon and add more mint if you like more or sweeten with sugar or honey if you like a sweeter popsicle. Keep adding and blending to taste.

Strain the watermelon juice through a fine mesh strainer. Do this in batches if you need to and discard the fiber/foam.

Pour the juice into popsicle molds. If some foam develops on top use a popsicle stick to remove or deflate the foam. There shouldn’t be a lot.

Place the cap on the molds and freeze. After about 2-3 hours, stick the popsicle sticks into the molds. By allowing the popsicles to par-freeze the sticks will stay in place and be even.

Freeze overnight.

Serve in wine glasses and pour cold prosecco over.
