The rumen inner wall meat column industry is commonly known as the "belly collar, belly beam, belly kernel" cardia dilator muscle, the meat is thick and tough, commonly known as the "belly tip", "belly" (soaked in alkaline water to make it crisp and tender, can be made into a vegetable alone).

How to deal with raw tripe.

1. Soak in warm water. Because tripe is similar to the stomach of other animals, soaking the impurities in the stomach with warm water can be soaked out (generally floating to the surface of the water) Note: Soak it three times in warm water, and add alkaline noodles to the warm water, because soaking in alkaline water can make the tripe crispy and tender, and cooking will be better.

Because there are many impurities in the stomach, it is generally difficult to remove the innermost impurities after soaking once.

2. Poke it with water. Because poking it with warm water can make the tripe softer and easier to cook, it will not taste so gluten, and it will become more flavorful, so it will taste more fragrant.

1. First use a handful of salt (granular form is better) to rub the tripe inside and out repeatedly to remove most of the mucus and dirt.

2. Add 2-3 taels of vinegar to continue kneading to remove most of the peculiar smells.

3. Wash with water and remove.
