A ripe watermelon will feel sturdy and have a resonant, satisfying hollow sound. That means it’s bursting with watermelon juiciness and is at its peak of ripeness. If the thwap is dull sounding or the fruit feels soft, pass on it.
Watermelons don’t continue to ripen after being harvested, unlike many other fruits, so it’s no good to just buy one and try to let it ripen on the counter.
A yellow or creamy underside indicates ripeness. If this area is white or pale green, it isn’t ripe yet. Scratch the surface of a watermelon with your fingernail. A greenish – white color beneath the outermost layer of the rind signifies a ripe watermelon.
Watermelon does not ripen after harvesting, but it can get mushy in the refrigerator if it is a little overripe when picked, even before you cut into it. Store uncut watermelons in a warm, dry place for two to three weeks. Once you have cut the watermelon, you can store it in the refrigerator for two to three days.
“In general, melons will not change significantly once they ‘re harvested from the vine,” Green explains. She says that cantaloupes, honeydew, and watermelon are all non-climacteric fruits, which means that once they ‘re harvested, they won’t continue to become tastier or sweeter like peaches or bananas will.
Use a knife to slice a lemon or lime in half and squeeze about 1 tablespoon (15 mL) of juice over sliced or cubed watermelon. Some people find that a boost of acidity makes the melon taste sweeter. Try adding salt and pepper to round out the flavor. Or, if you like spicy foods, add some cayenne or hot sauce!
According to Treehugger, unlike other fruits, watermelons don’t continue ripening after they’ve been picked, so your best bet is to avoid choosing an unripe melon if you can. Eating watermelon that isn’t fully ripe isn’t dangerous, but it’s not as good as a ripe melon.
Like any fruit, it will last well if you leave it on the vine, but that doesn’t mean you should leave it forever. The plant will cut off water and nutrient supply to the fruit after it’s ripe, and the fruit will start to lose its flavor and sweetness, and it will eventually start to decay in the heat.
Another important thing to look for the field spot. This will be a yellow splotch on the underside of a watermelon. It should be a creamy yellow colour. The darker the yellow, the sweeter the melon is!
Sultan is one of the sweetest varieties you’ll find, this one measures 12.3 on the Brix scale. The fruits average 15 pounds and ripen within 95 days.
If you have a watermelon that is not as sweet as you like, sprinkle it with a little bit of salt to bring out the fruits natural sweetness.
A watermelon can be stored in the refrigerator for 2 weeks, and sometimes as long as 3. When storing a cut melon, wrap the cut side in plastic, and it should keep in the fridge for about 3 days. The plastic will prevent the watermelon from absorbing the flavors of other foods and will keep its flesh moist.
