Here's a rookie cookery tip for you: Cutting up a clever serving bowl out of the watermelon rind is NOT like carving a pumpkin. I found this out the hard way, when I decided that I would finally make one of those artfully carved melon bowls by slicing the little zig zag pattern directly into the watermelon, just as if I were carving the big grin on a jack-o-lantern....and then trying to pry the thing apart without destroying it. This was unwise, but somehow I mangled--I mean I managed it.
In retrospect, what I should have done was simply slice the watermelon neatly in half, in a straight line. THEN I could use the melon baller to empty out the rind, THEN I could have carved the artfully shaped rim.
As it turns out, one big watermelon yields a large number of melon balls, so I had plenty to fill the bowl for this fruit salad, plus some left over. I also carved a couple of cantelopes into the mix, and garnished it with some fresh mint leaves from the garden. This was a big hit at the picnic, as well as finally providing me with a chance to use the melon baller (and give my right forearm a workout!). Everyone needs to do this at least once, don't you think?
