1. Buy the boxed beef tenderloin that was fresh on the day in the supermarket. If it is frozen, let it thaw naturally. Don't turn it in the microwave oven and put it in the water to thaw it, which will affect the meat quality.
2. Prepare vodka and onions, potatoes and other corresponding vegetables. The steak is perfect with red wine. Potatoes and vegetables are cooked in advance.
3. Heat the pan on high heat, pour in a small amount of olive oil, put in the steak after the oil smokes, drag the steak with a shovel for about 30 seconds, turn it over and continue to drag with the shovel, pressing the steak with the shovel blade from time to time . This way, the steak can be cooked faster. Second, the elasticity of the steak can be measured somewhat cooked. This is the key experience of frying steak. (If the meat has no elasticity when it is pressed down, it is old, otherwise the more elastic the meat is not cooked)
4. Then, pour olive oil in the pan, heat the oil, add onion rings and stir fry (if you like butter, put butter), add a small amount of light soy sauce, stir fry, and pour it on the steak.
5. Sprinkle with black pepper and squeeze with lemon juice.
6. I like the eight mature ones, which are reddish in the middle of the cut, with red gravy flowing out.
