I’ve spoken with many middle aged Chinese people who have reported that for as long as they can remember, even growing up on a farm, they would never drink milk, even their own cattle’s, without first boiling it on the hob firstly. Yet many make claims that until later this century nobody ever pasteurized milk.
I’m mainly interested in Eastern Chinese cultures, but then realized that throughout history this might have been less well defined and even now is relatively broad. For that reason I wouldn’t mind comparative remarks on for example Mongolian, Korean, or Russian (or even Tibetan or Xinjiangese cultural traditions. Please feel free to scope your answer however it will seem most sensible and insight-yielding to do so.
Lastly please forgive my ignorance but I simply have no idea where I would start in trying to look for answers to this myself.
