Selection skills of litchi:
There are many thorns on the surface of litchi, and these thorns will not hurt people to the touch. But if it is sharp, it is also painful to tie people up. So we can look at the burr on the surface of litchi when we buy it. Generally, if the burr is deep and sharp, this kind is very mature and tastes sweet. If the burr of litchi is shallow, it may not be so sweet and the water is not so sufficient.
Everyone knows that litchi is blue when it is immature and red when it is ripe. We can also judge whether it is mature according to its color. Most lychees on the market now are relatively red. If there are green lychees, they may not be fully mature and will have astringent taste.
