Watermelon is 92 percent water, making it almost as thirst-quenching as an actual glass of water. (Ancient Egyptians, who knew something about desert heat, began harvesting watermelons nearly 5,000 years ago.) With Aug. 3, National Watermelon Day, on the horizon, it’s time to consider the many ways you might enjoy the unofficial fruit of hot, hot summer.
Seedless varieties, which are not the result of genetic engineering but are in fact the product of the age-old practice of cross-breeding, now make up about 85 percent of the watermelon market. That’s bad news if you want to have a seed-spitting contest, but great if you’d rather not pick seeds out of your salad or if you plan on pureeing your watermelon for a smoothie.
Choose a melon that has a creamy yellow spot on its underside, where it rested on the ground while ripening. It should feel heavy for its size and make a hollow sound when tapped, both indications that it is juicy. A whole watermelon will keep on your countertop for a week or so, longer if you store it in the refrigerator. Cut up and stored in an airtight container, watermelon pieces will stay fresh for 3 to 5 days.
Watermelon Caprese Salad: This is a great alternative to the popular tomato and mozzarella salad when tomatoes aren’t yet available, or when you want an even juicier version of the classic. Simply substitute thin slices of watermelon for the tomato (you can even cut them into circles with a biscuit cutter so they are round) and alternate them with slices of fresh mozzarella on a platter. Finish with a drizzle of olive oil and just a few drops of balsamic vinegar, a shower of basil leaves, and a sprinkling of sea salt. A fun variation: Use tiny balls of mozzarella (called ciliege) and cut the watermelon into tiny balls with a melon baller.
