According to the public health network, shrimps are usually boiled in white water. Generally speaking, the heating time varies according to the size of shrimp. After boiling, add shrimp. If the shrimp is big, it will take about 5 minutes. If the volume is relatively small, it usually takes 2-3 minutes. When the shrimp turns red, it means it has been cooked for 10 minutes. Don't cook green shrimp in cold water, so the nutrients of shrimp will run into the water and the shrimp itself will not be fresh. Be sure to wait for the water to boil before putting the shrimp in for ten minutes. Fresh shrimp itself contains bacteria. Boil shrimp with less water, which is about a quarter of the weight of shrimp. After the water is boiled, put the shrimps into the pot until all the shrimps turn red, and there are cracks and a little protruding meat in the shrimp shell.
