lemon
If you want to say the sourest fruit in the world, it must be lemon. Although the taste of lemon is sour, it is rich in nutrition. Eating lemons often will make our skin very white and our skin will be much better. Lemon can also accelerate gastrointestinal peristalsis, and can also decompose excess fat in the body, making us slim down invisibly.
green plum
Plum is a fruit that many rural children have eaten, but it is rare in cities. However, plums are usually made into dried plums, which can also be seen in supermarkets. Dried plums are not particularly sour, but plums are really sour. To tell the truth, they are similar to lemons. People will eat once and never eat again. In rural areas, plums are not used for eating, but made into plum wine or dried plums, so that the taste will not be too sour and acceptable, otherwise fruits like this will sour their teeth sooner or later.
red bayberry
Speaking of plums, let's talk about bayberry, bayberry and plum. Although they all have plum characters, they are completely different fruits. In the idiom "Looking at plums to quench thirst", I don't know whether plums quench thirst or waxberries quench thirst, but it can be proved that both kinds of plums are sour and refreshing.
Passion fruit
We can barely eat one or two of the above four fruits, but we don't even want to eat a bite of passion fruit. It is too sour. I haven't eaten it before. I bought some from the supermarket and checked the way of eating online. When I got home, I tried it with a spoon and threw up directly. If someone can eat this passion fruit like this, I really admire it! Call him big brother!
