1. Take two fresh sweet potatoes with yellow hearts (the sweet potatoes with glutinous varieties taste better), peel and cut them into pieces after washing, and cut them slightly thicker, which is similar to the thickness of the pencil shell. Try not to cut them too thin, otherwise they will be easily broken after cooking and affect the taste.

2. add a proper amount of water to the pot and pour in sweet potato pieces. the water can cover the sweet potato a little more.

3. after boiling water on a large fire, skim off the floating foam generated in the pot after the water boils. Cover the pot and simmer for 5~8 minutes. If the sweet potato is in large quantity, you can cook it for a few more minutes.

4. When it's almost time to cook, open the lid and try to insert the sweet potato with chopsticks to see if it's ripe. If the sweet potato has cracked or broken by itself, it means it is ripe. At this time, you can change the fire and add the right amount of salt to taste. Stir well and serve.

5. Friends who like to eat chopped green onion can sprinkle a little chopped green onion before the sweet potato is cooked, which is more fragrant.
