Prepare ingredients: goat brain, scallion, salt, pepper, soy sauce, starch, aged vinegar and sesame oil.

1. Don't choose mutton that is too thin, but it is better to choose this kind of fat and thin, such as mutton on the brain, which makes the dish more fragrant; Don't cut the mutton too thin, just about two coins thick, because the meat of mutton is tender, and if it is cut too thin, the taste of mutton will be hard.

2. Add salt, white pepper, light soy sauce and dark soy sauce to 35g of cut mutton, grab and stir until it sticks to your hands, then add about 3g of pepper water, add a spoonful of starch, continue to grab and stir, thinly paste the mutton, and finally add 1g of sesame oil and mix well to lock the moisture. Many friends like to put cooking wine when curing mutton. Cooking wine has a strong aroma and spicy taste, but it is not suitable for curing mutton. We only need to soak a bowl of pepper water in advance to remove the fishy smell of mutton.

3. The green onions in season are cut into such hob blocks.

4. The key to the delicious mutton with scallion is the juice. If you adjust the juice in advance, it will not only serve quickly, but also taste better. Add a teaspoon of soy sauce, a teaspoon of oyster sauce, half a teaspoon of pepper, a little soy sauce, a little starch and half a bowl of pepper water to the bowl and mix well.

5. Heat the pan first, and then put the oil, so that the sliced meat is not easy to stick to the pan, and the oil is slightly more than usual. When the oil temperature is 4% hot, add the sliced meat, use chopsticks to spread the sliced meat, and then slide all the sliced meat until it becomes discolored.

Mutton is easy to cook, so don't worry about the undercooked mutton. You can take it out if it changes color completely. If you slide the sliced meat for too long, the taste of mutton will become old and dull.

6. Leave a little base oil in the pot, then stir-fry the chopped green onions in the pot and stir-fry the fragrance of the green onions. The whole process takes about 1 minute.

7. Stir-fry the green onions until fragrant, then add the mutton that has been cooked in advance, and then add the prepared sauce along the side of the pot, stir-fry for more than ten seconds with high fire, and stir-fry until fragrant and tasty.

8. To make sauteed mutton with onion, add a little Shanxi mature vinegar before leaving the pot, and add it along the side of the pot to cook the aroma and let the sour taste evaporate, so that the taste and taste of the dish will be better.
