Facial collagen

First put the pig skin in boiling water and boil it for a while, remove it, use a fruit knife to scrape off the oil (there is a thick layer of fat on the surface of the pig skin that must be cleaned), and use a fruit knife to scrape it until there is no white color, then use a bone cutter to cut it into grains (the pig skin is very hard, so it is easier to operate with a bone cutter).

Prepare a soybean milk maker (I use Jiuyang's), pour the cut pig skin grains into the machine, add water, and press the "Five Grain Soymilk" file.

About twenty minutes later, the pig skin grains are processed by the soymilk machine and become this milky white liquid. There are also some very broken precipitates. It doesn't matter, it can slowly melt away after boiling them.

Put it in a saucepan (you can't use an iron pan or aluminum pan) and don't need to add more water, because a lot of water has been added when beating. Bring to a boil over high heat, cook over low heat, until it is finally boiled into a bowl (just use a spoon to scoop it until it is very thick), pour it into a container (be sure to pour it while it is hot), let cool, wrap it with plastic wrap, just put it in the refrigerator.

This is frozen pig skin. You can take it out and chop it up and eat it, or you can spoon it directly. Eat it every day. Gradually, you will have a surprise discovery.
