Cows have 4 tripes, which are the rumen, reticulum, omasum, and abomasum. The rumen, reticulum, and omasum do not have gastric glands and do not secrete gastric juice. Their functions are similar to the esophagus. The abomasum has gastric glands that secrete digestive juices, similar to the human stomach, and is also called the abomasum. Because their structures are different, the tastes of the four stomachs are also different.

The rumen is cow tripe. It has pimple-like protrusions on its surface and has a tougher texture. It is suitable for stewing, boiling, and cold dressing.

The reticulum is also called the honeycomb stomach, which is also the money belly. There are honeycomb-like and mesh-like protrusions on the surface, and the taste is relatively tough, because the nest-like structure can effectively retain the juice, which is easy to absorb and is suitable for stewing.

The omasum is the tripe, louvered tripe, commonly known as beef tripe, tripe tip, etc. There are many lobes of different sizes, with a large number of thin flaps on the surface, with small protrusions, and a crispy taste. The multi-petal structure and small protrusions have a strong ability to retain juice, making it suitable for cold dishes or hot pot.

The abomasum is also called cow tripe and sand melon tripe. It has the toughness of cow tripe and money tripe, but also has a rich and wrinkled structure, which is suitable for stewing.
