1. Sweet potatoes are easy to change color, so it is best not to scald them when peeling. I peel them with a ceramic knife.

2. Here comes the trick! Cut peeled sweet potatoes into hob blocks, soak them in clean water for 4-5 hours, and change the water several times. The sweet soup cooked in this way not only won't change color, but also the sweet potato is softer and more delicious! Lily soaked her hair in cold water.

3. soak the sweet potato, then treat the cherry before preparing it, and push the cherry core out with chopsticks.

4. Soaked lily, two pieces of licorice and a small piece of ginger.

Don't use an iron pot for this sweet soup, otherwise the iron will react with starch and turn black easily. Pour a little olive oil into the pot.

6. Add ginger slices, stir-fry and remove.

7. Add potato pieces and stir fry

8. Add water to the sweet potato, add two pieces of licorice, boil over high fire, skim off the floating foam, and turn to low heat for stewing.

9. When the sweet potato is cooked until Microsoft is rotten, add rock sugar. Because licorice is reserved, there is not much rock sugar, so skim it again.

10. Add the lily soaked in advance. At this time, the red color of sweet potato has gradually brightened ~

1 1. Simmer until the sweet potato is soft and rotten. Then leave the fire, add cherries, let stand for a while, and you can eat!
