I think it's better to blanch. However, blanching can be divided into long-time blanching and short-time blanching according to personal interests.

Braised pork is the most common "hard dish" and the most common home-cooked dish, but when cooking braised pork, it is not clear to many people whether to blanch it or not.

there are actually two kinds of blanching, one is that the blanching time is short, as long as the floating foam is removed, and the other is that it takes a long time to cook. People with sensitive noses usually choose the blanching time for a long time, because it will have no fishy smell, but many people like to blanch for a short time and stir-fry lard.
