The so-called Zhang Fei beef is actually preserved beef. Zhang Fei beef can be made at home according to the production process of bacon. The following is the production process:

1, cut the beef into pieces of about 1 kg.

2. Coat the surface with salt and pepper. The amount of salt must be enough, or the meat will rot.

3. Put the beef into the pot and wait for its salt to penetrate slowly. It will take at least a week.

4. Hang the beef that has eaten enough salt and air dry naturally. It takes about a week to air dry.

5. Prepare cypress branches that can burn 1 hour, light the branches, and manually control the flame size to keep the flame out. At this time, cypress branches will release a lot of smoke and high temperature. Hang the air-dried beef on this pile of cypress branches and roast it for about an hour, and the beef will turn black.

6. Hang up the roast beef again and air-dry it for a day until the smoke clears.
