Buffalo milk is the best However, the general supermarkets can't buy it, so you can use all brands of pure milk. Just a little higher in fat. Don't recommend the brand. Now I don't trust national brands very much, hehe. However, I have tried a method of adding concentrated milk to make double-skin milk before, that is, although pure milk is used, full-fat milk powder is added to it, which seems to make it easier to produce milk skin. You can try it.
