Materials: pig brain 1 piece, 5 red dates, a little medlar, gastrodia elata 10g, peanut oil and salt.

Step 1: Prepare 1 pig brain. Generally, you should make a reservation with the stall owner who sells pork in advance. Soak the pig brain in water for half an hour and then wash it. It seems difficult to pick out the blood tendons and other things on it, but it is actually easy to peel them off. Patiently peel it all off, clean it, rinse it off, and then put it in the stew pot.

Step 2: Prepare 5 red dates, a little Lycium barbarum and Gastrodia elata 10g, clean these medicinal materials and remove the red dates. The red dates in the stew must be removed, because it is high in calories and easy to make people feel dry.

Step 3: Put all the cleaned medicinal materials, together with pig brain, into the stew pot, and then add appropriate amount of water. The small saucepan I use here is enough for boiling 1 pig brain and adding 2 bowls of water. The saucepan won't dry much water. It's not necessary to add too much water when adding water, but you must never add water to the stew halfway.

Step 4: Cover the pot. After the fire is simmered, turn to medium heat for one and a half hours. If the power of the large saucepan is high, you can stew 1 hour, and then leave it for ten minutes after turning off the fire.

Step 5: When the time is up, just add the right amount of salt and a little peanut oil to taste, without adding other seasonings. The soup is very rare and sweet. If you eat pig brain, add some salt and oil, it will taste better.
