Go to the supermarket to buy a steak first, and be careful not to bring too many white tendons.
2. Sprinkle black pepper on both sides of the steak, evenly spread a little salt (because you need to make sauce at the back, you can put less salt), and then evenly pour in olive oil (peanut oil, corn oil is also ok).
3. Burn the pot until it smokes, put the steak in the pot and press it with a clamp to ensure that the beef is heated evenly. Fry each side for 1-2 minutes (the thick meat can be fried for a long time, but the thick meat can't exceed 4 minutes, otherwise the beef is too old to bite), so it is medium-cooked, with powder on the outside and no "blood". Put the cow on the plate, add some vegetables and serve.
