If the trotters want to be soft and waxy, the heat is very important.

First of all, after cleaning the trotters, put them into a pot with cold water, and add enough water at one time, without adding water in the middle. First, cook them over medium heat, and then simmer them over low heat. Secondly, the added materials, adding appropriate amount of rice vinegar and garlic, are conducive to making trotters softer and more nutritious. Finally, after the trotters are stewed, turn off the fire and stew for a while, which will be more delicious.
