Preparation materials: purple potato, water, etc.
1, to buy a good purple potato, it is best to cook the purple potato in a moderate size. If it is too big, it is easy to cook, and if it is too small, it is difficult to grasp the cooking time. At the same time, we should also pay attention to whether there are insect eyes or brown spots on the skin of purple potatoes, which are not good.
2. Wash the purple potato with clear water and remove two extra long roots.
3. Wash the boiling pot and put the purple potato into the pot.
4. Add an appropriate amount of cold water to the pot, and the amount of water is generally almost the same as that of the purple potato itself. Then you can start cooking with fire. It's best to cook slowly over medium heat, so that the purple potato cooked is not easy to break the skin, or it can be boiled over high fire and then cooked over medium heat.
5, the cooking time depends on the size of the purple potato itself and the amount of cooking. Generally, cooking at home takes about 15~20 minutes. If you feel bad, you can stick it with chopsticks. If you can easily insert it, it means that the purple potato is ripe.
