2. Take out the newly bought mutton, clean it and let it stand until the moisture on the surface of the mutton is dry.
3. After drying, put it in the refrigerator for freezing. When frozen in the refrigerator, if the refrigerator at home has a temperature change function, you can put the mutton in the cabinet with a temperature change function.
4. Observe frozen mutton. When the mutton hardens, it can be cut into rolls. Be careful not to freeze too hard.
5. Take out the moderately frozen mutton, put it on the chopping board and start to cut into rolls. When cutting mutton, try to ensure that the thickness of the cut mutton roll is moderate, and the thinner mutton slices can be automatically rolled.
6. After the mutton is cut, you can put it on a plate or bag it, put it back in the freezer of the refrigerator and take it out when you use it.
