Generally speaking, it takes 10 minutes to 15 minutes to cook potatoes.

Pay attention to the following points when cooking potatoes: 1. Potatoes that can't germinate will be poisoned. Ask for fresh potatoes and wash the skin. 2. When preparing materials, it is best not to remove the potato skin, because removing the potato skin and cutting it will lead to the obvious loss of nutrients such as potassium. 3. After it is put into water, it should be cooked with slow fire, and it will be cooked evenly, and it will not be tender outside. 4. After cooking, peel it and eat it, because potato skin is the part with the most alkaloids. It is best to remove it before eating, so as to avoid taking in too many organisms. Dieters should pay attention to eating potatoes as staple food instead of dishes, and should not eat too much. Third, normal consumption can be used as a staple food, because potatoes are nutritious, rich in starch and low in fat. You can eat some potatoes every day, reduce the intake of fat, and gradually metabolize excess fat, which will not be harmful to your health. Potatoes can make up almost all the nutrients needed by the human body, and at the same time, rich cellulose can make the stomach swell and feel "full of wine and rice".
