roast beef

Let the beef go to room temperature for about an hour. In a frying pan without oil, cook the sides of the beef 30 to 1 minute each time. Sprinkle pepper all over.

Once you have taken out the grilled beef, put it in a plastic bag, add [A] and let the air out of the bag. (If you soak the bag in water, the air will escape due to the difference in temperature. It's better to put your mouth against the mouth of the bag and inhale the air inside.)

Put [2] in styrofoam, pour boiling water (boiled water with about 20% of water), cover it with a lid and wait for 15 minutes.

After 15 minutes, the beef is removed from the bag and the pickled sauce is placed in a frying pan. Cut the beef against the fiber and arrange it flat on a plate.

Warm the sauce in a frying pan and add water-soluble potato starch to make it thick.

Place grated apples in the center of the plate and start spinning the sauce to finish.
