Combine watermelon chunks and Everclear in a glass jar with lid.

In a small pot, combine lime juice, sugar, and water. Over medium heat, stir until sugar is fully dissolved (no need to bring it to a boil). Remove from heat and allow it to cool down.

Pour simple syrup into the jar.

Allow it to sit in the refrigerator overnight or up to 48 hours.

Pour contents of jar into a bowl and mash the watermelon with a potato masher, then strain mixture back into the jar.

Add in ½ cup of the Watermelon Pucker. Shake, taste to see if the flavor is to your liking. If not sweet enough or watermelon tasting enough add in additional Watermelon Pucker.

Store in your freezer until ready to enjoy.

Note: Always leave headroom in the jars for expansion. The mixture should not truly freeze up, however, err on the side of caution. Freeze overnight (or longer).
