Not as sweet as common watermelon pickles, and fantastic on turkey sandwiches (and don't forget to use the onions!). You can use cucumbers instead, but I prefer the firm texture of watermelon rind. (For crispness, I soak the cubes in a little alum and water, which is not recommended any longer.) If you leave the cubes big -- or even cut the rind into spears -- they're delicious straight from the jar and on relish trays.
