Soak the tremella in water first. I usually soak at noon and cook at night. Sometimes it is soaked before meals and cooked after meals. In other words, it is as short as one hour and as long as five or six hours.

Wash tremella with clean water for two or three times after soaking, and control the water. Remove the yellow root of tremella, and tear tremella into small pieces by hand.

2. Lotus seeds, red dates and medlar are also soaked in water. This won't take long, usually more than ten minutes. I usually soak them before cooking, and then I start cleaning tremella and tearing pieces. Tremella has been processed, and lotus seeds, red dates and medlar are almost the same. Control the water after soaking.

Tear the red dates with your hands to expose the pulp. This is done to make the sweetness of red dates easy to come out.

3. Add cold water to the pot, and put the tremella, lotus seeds, "meat-exposed" red dates and medlar together. When the water boils, turn the heat down and start to cook slowly. Be careful not to open the lid too wide, or it will dry easily.

You can smell the red dates soon, but don't worry, it will take at least an hour and a half to cook. Add rock sugar when it is almost cooked, according to personal taste. Because the bought red dates are very sweet, they are rarely put.

5. After the rock sugar is put in, stir it. In a few minutes, delicious nourishing soup can be cooked. It is really delicious!

Note: the volume of dried tremella and soaked hair is very different. If you don't particularly like eating tremella, don't be greedy when soaking.
