1. Soak it in boiling water first. Don't cook it for too long here, as long as it can peel off the hard skin on the surface of the beef tongue.

2. Cut the beef tongue obliquely, and don't cut it with a straight knife. The thickness is about 1-2 cm. Too thin and too thick is easy to fry.

3, add butter to enhance the fragrance, slowly fry, fry until there is no blood on the surface, not too long, otherwise it will be old.
