Material preparation: beef, black pepper, olive oil, 3 tbsp salt, oil consumption, egg white, red wine, starch, finger twist soda, etc.

1, prepare beef tenderloin, preferably this oily belt.

2. Slice, about 1cm thick. Wash it clean, dry the kitchen paper, and the thickness of the knife is not good. Massage steak piece by piece, that is, knock the meat loose with a light hammer.

3. Find a big bowl, which is bigger than the steak. Add all seasonings and stir well.

4. Wrap the steak in seasoning and massage gently! Put in a fresh-keeping box, sprinkle some black pepper on each piece, cover the fresh-keeping box and marinate for 48 hours.

5, take out the marinated steak, the sauce will absorb some water, turn into a gel state, and the meat will turn black. Choose yellow oil frying, the milk is more fragrant.

6, slow fry on a small fire, otherwise it will be easy to paste.
