Cut up the watermelon into bite size cubes and place in a large bowl (I used Tupperware, so I could seal it later).

In a 2-cup liquid measuring cup or a coffee mug (or whatever), add the leaves from 2 sprigs of mint, the juice of 2 small limes, and 1 tbs of agave. With a citrus reamer (pestle, or the flat side of spoon), crush the mint leaves into the mixture to release their flavor. Pour mixture over the watermelon, add a pinch of sea salt, and mix by hand, coating evenly. Tear the leaves from the two remaining mint sprigs into small pieces and mix in. Seal the bowl and refrigerate for one hour. Then drain the liquid from the bowl and transfer it to the freezer for one hour, or to desired chillness. Serve and rejoice.

Caveat: I should add that the whole melon-citrus thing is not ideal food combining, so if you’re especially sensitive to that kind of thing, you might want to skip this one. If you’ve got a stomach like Chuck Norris, proceed.
