I remember that, when I was touring Russia & Siberia in my capacity as "Momager" to daughter Ruth during her performing days, whenever our hosts knew we were English, they would always insist on making us tea (if not vodka), and as milk was an unavailable commodity, we were always treated to a heaped spoonful of red jam, to sweeten the brew. It tasted weird to me at first, but I gradually became used to it. The only people who were permitted to have milk were babies and old folks. I never saw a cow anywhere during our travels. Evidently, they are kept behind closed doors, for their protection, from the milk hustlers!
