Potato chips can be tied with chopsticks to make sure they are cooked. If they can be inserted easily, it means they are cooked. If potato chips are not cooked, it will cause poisoning, because the content of solanine in potatoes that are not fully cooked is relatively high. When ingested into human body, it is easy to cause solanine poisoning and red blood cell agglutination.

Specifically, we also need to look at the thickness, quantity, degree of heat and the pot used. Generally, cooking the potato until it changes color means it is ripe.
