How to eat potatoes

Don't eat sprouted potatoes. Potatoes that have germinated are forbidden to eat, and a large amount of them can cause acute poisoning.

Peel and dig holes. When eating potatoes, you must peel them and dig the parts with buds. Potato skin contains alkaloids, which can cause nausea and diarrhea when eaten in large quantities. Potatoes are easy to oxidize and turn black after cutting, which is a normal phenomenon and will not cause harm.

Soak in cold water. Peeled potatoes can't be cooked immediately, so they should be soaked in cold water to avoid oxidation and blackening, but be careful not to soak them for too long, resulting in the loss of nutrients such as water-soluble vitamins.

There are often blue spots on the surface of potatoes, which are not beautiful when serving. For example, if you put some vinegar (one tablespoon per kilogram of potatoes) in the water where potatoes are boiled, the spots will disappear.
