The front and back elbows of pigs can be distinguished from four aspects: the shape, the thickness and position of the elbow bone, the cross section of the elbow bone, and the thin end of the pig. Elbow refers to the hinge joint connecting the upper arm and forearm, while the pig elbow is at the foot joint. No matter where you are, elbow is the main dish at the banquet, but the taste of the two kinds of dishes is different, so you need to distinguish them carefully when buying.

1. Different appearance. The pig's front elbow is in the shape of a regular cone; the pig's back elbow is shaped like a semi-truncated cone, with one end thick and the other thin. The pork elbow is more beautiful and regular.

2. Look at the thickness and position of the elbow bone. The elbow bone of the front elbow is relatively thin, and the elbow bone runs through the middle of the elbow, and is surrounded by more pork. The most typical feature is "median bone, thin bone, and more meat"; the elbow bone of the rear elbow is relatively thick, and the elbow bone runs eccentrically. , located on one side of the elbow, one side is wrapped by pork and the other side is wrapped by pig skin and fascia. The most typical characteristics are "eccentric bones, thick bones, and less meat".

3. Look at the cross section of the elbow bone. When cutting off the pork elbow bone, the front elbow generally cannot be cut off from the joint, and is usually cut off directly. Therefore, the thick end of the elbow bone of the front elbow is cut off and has bone stubble; the rear elbow can generally be cut at the joint, so the thick end of the elbow bone of the rear elbow has a smooth elbow bone articular surface.

4. Look at the fine end features. The thin end of the front elbow is relatively straight, with a natural and free curve; the thin end of the back elbow has a curved elbow joint and a steep right-angled curve.
