Cut the mutton into strips with a knife, and its cross-sectional area is the size of the mutton roll you want. Preferably square. Then wrap the mutton tightly with plastic wrap and put it in the freezer, freezing 1 hour (-18 degrees). Wait until the meat is completely frozen and the surface is frozen before cutting.

Generally, there are mutton roll cutters, so just give them a processing fee. If you need to use it frequently, you can buy a small slicer for your family if you can.
