Steps:
1. Get all the ingredients ready and weigh them first. Peach gum and snow swallow need to be soaked 12 hours in advance. The temperature is high in summer, so they go bad easily. They need to be soaked in the refrigerator and the water needs to be changed twice.
2, Gleditsia sinensis soaking time is short, 6-8 hours is enough. If you observe more, the bubbles will rise, and you will not have a hard heart.
3. Clean the soaked Swift, Gleditsia sinensis and Peach Gum to remove impurities. I put peach gum and snow swallow in a colander, wash them separately, and then clean up the impurity black spots with tweezers. Use stainless steel pot or enamel pot to put proper amount of water, first put peach gum, and then put honey locust into the pot.
4. Cover the pot, turn off the minimum heat after the water is boiled, and cook for about 20 minutes.
5. Open the lid to see that the soup is a little sticky, and then put the washed snow swallow into the pot.
6. Wash the red dates, put them into the pot, then add the rock sugar, boil and turn to low heat, and simmer for 10 minute.
7, this step should pay attention to, turn to the minimum fire after boiling, don't cover the lid, stir with a spoon at any time, to prevent sticking to the bottom of the pot. Because peach gum, honey locust and snow Yan Dou are gelatinous and rich in collagen, if they are not stirred, they will definitely paste the pot.
