Hello, it is really easy to add something to the barbecued pork outside. Generally speaking, if you buy bagged barbecued pork in the supermarket, you will find that it contains food additives, sodium nitrite, red yeast and other similar substances. After adding it, the food will not go bad easily and the color will be bright. Usually soy sauce is difficult to color, so choose soy sauce, which can be used to color. Dark in color, it is a useful seasoning for coloring.
I hope it is useful to you, and I hope to adopt it ~
