1. Wash tremella, jujube, lotus seeds and medlar, and put them in a bowl for soaking. Change water 2-3 times in the middle, and soak 1 hour. Because it is an electric pressure cooker, you don't have to soak it for too long, otherwise the tremella will melt.

2. Add enough water to the pot, remove the root of tremella and put it in the pot, add lotus seeds together, add 3-4 pieces of old rock sugar, cover the pot, and make porridge, usually for 25 minutes.

3. Wash and soak raisins and lily slices when cooking porridge. After 25 minutes, when the silver is familiar, deflate, open the lid and put the red dates, medlar, raisins and lily slices into the pot, then cover the pot and set the cooking time to 10 minute. Remember not to deflate after the second time. When it cools naturally, open the lid and you can eat.
