1, potatoes are boiled directly in the pot. Generally, it takes about half an hour or 40 minutes to cook until soft. So it takes a long time to cook potatoes directly until they are soft. Cut the potatoes into pieces and cook them in water. If the fire is big, you can cook them soft in four or five minutes.

2, cold water and vinegar: potatoes are peeled or cut. If you can't eat them right away, you need to add some vinegar to the cold water so that the potatoes won't turn black.

3, hot water soaking is easier to peel: just bought potatoes are not easy to peel, you can soak them in hot water first, and then put them in cold water, alternating hot and cold, potato skins are easier to peel.

4. Store in a cool place: Potatoes can't be protected from light and need to be stored in a cool and dark place. When potatoes are exposed to the sun, they will turn green and affect the taste.
