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.
- To prepare the melon, use a spoon to scrape away all the pink.
- Cut away the rind with a knife (this is fastest if you cut the melon into 3-inch squares).
- Cut rind into strips, cubes, or chunks.
- Layer the MELON and onion with salt in a large bowl; cover with ice cubes.
- Let stand 1 1/2 hours.
- Drain and rinse.
- Combine remaining ingredients in a large pan and bring to a boil over medium-high heat.
- Add the MELON and onions and return to a boil.
- Pack hot PICKLES into hot, sterile jars, leaving 1/4-inch head space.
- Fit with lids.
- Process in boiling water for 10 minutes.
