Tips:
1, cleverly argue that the watermelon is ripe: hold the watermelon in one hand, pat it gently with the other hand, or play with your index finger and middle finger. Mature watermelons will have a dull sound when knocked, and immature watermelons will be brittle when knocked; The general rule is that cooked melons are "muffled" and raw melons are "crunchy", but some melons are too thick to knock, but they are not necessarily cooked melons.
2, the skill of cutting ripe watermelon: the ripe watermelon skin is thin and big, and the knife will burst when touched lightly, which is ugly and not easy to eat; If you poke a hole about seven or eight centimeters at the bottom of the watermelon with chopsticks, turn it a few times, then pull out the chopsticks, cut it from the hole with a knife, and cut the watermelon as usual, you will cut a semi-flat watermelon.
Watermelon is an excellent fruit in summer, and its seeds can be used to make tea. In cooking, watermelon is used to make ice bowls, watermelon cheese, watermelon cakes and so on.
Watermelon is a summer melon, which should not be eaten in winter, and should follow the seasonal law.
Don't eat the watermelon just taken out of the refrigerator.
Selection skills of watermelon
1, look at the color and listen. Melons with smooth surface, clear patterns, obvious lines and yellow bottom are ripe melons; The surface is fluffy, dull and mottled, which is an immature melon; Playing a melon with your fingers and hearing the sound of "pengpeng" is a ripe melon; Those who hear the sound of "Dangdang" are not ripe, and those who hear the sound of "poop-poop" are ripe melons.
2, look at the melon handle. Green is ripe melon; Dark brown, fluffy, fragile, curly beard tip turned yellow and withered, which is a melon picked prematurely; The handle of the melon has dried up and it is a "dead vine melon" with poor quality.
3. Look at the head and tail. The two ends are symmetrical, the navel and pedicel are deeply sunken, and the good melon is full around; The quality of melons with big head and small tail or thick pointed tail is poor.
4. Specific elasticity. The skin of melon is thin, and it is fragile when pressed by fingers, which is a ripe melon; Scraping with nails will crack, and the melon will be soft and ripe.
5. Use your hands. Those who feel empty are ripe melons; All that feels heavy are raw melons.
6. Try the specific gravity. It is ripe melon that floats when thrown into the water; It is the raw melon that sinks.
7. Look at the size. The same variety, the big one is better than the small one. There is a certain relationship between the size and maturity of watermelon. The giant watermelon is not the earliest ripe, but it is definitely not the latest ripe, usually in the middle of watermelon ripening. Therefore, before most watermelons go on the market, it is more likely to buy small and medium-sized watermelons to mature, while it is less likely to mature large watermelons. By the same token, when watermelons are on the market on a large scale, it is not appropriate to buy small melons instead of big ones. Small watermelon may be the abortive vine of early-maturing variety (early-planted watermelon).
8. Look at the shape. The melon body is neat and symmetrical, grows normally and has good quality; Melons are deformed, grow abnormally and have poor quality.
9. Look at the melon skin. Xin Jing No.1, a light green melon skin with dark green net stripes and a nearly spherical figure are their signs. There is also a black beauty. Black-green, slim watermelon is also a sign of choice. In addition, there are some popular varieties in the market, such as Chunhongyu and Jin Xiaofeng.
It should be noted that the quality of a watermelon is fundamentally determined by genes. These varieties mentioned above have been cultivated and selected by gardeners for a long time, and there is a higher chance of producing watermelons with higher sugar content and more water from the beginning of seed germination.
10, observation plant method. Looking up and down from the vine where the melon field is located, it naturally dries up, indicating that the growth of watermelon has naturally ended and the watermelon is mature.
