lol I suppose if there's a potential sexual/ fetish element to it, Free-for-All is the best place for it. I just felt weird giving my kid something when I had no idea what it was like. lol It could have tasted nasty or something. :o Royalty has official food tasters.
Soy "milk" and rice "milk" are not really "milks" by definition.
But there's quite a few other mammals that are used for milk production. There's horse milk (popular in the Mongol part of Russia), caribou (reindeer) milk (consumed in Scandinavia), camels milk (middle east), buffalo milk (Asia), donkey milk, yak milk and sheep milk (which makes a great cheese for you pasta, by the way).
My own personal favorite is produced by Guernsey cows. Brown Swiss and Jerseys are right up there in quality too. The milk is a pale yellow because of the very generous butterfat content, which enhances the flavor. But most milk these days comes from Holstein cows which go for quantity, no quality. In fact the butterfat content is sometimes so low in Holstein milk that some dairy farmers run a few head of one of the breeds that I mentioned to keep their butterfat content up to snuff (Butterfat content determines how much the farmer is paid for his or her milk).
I do not often drink milk, but I have only tried cow's milk. I do not want any soya or rice milk. They lack complete proteins, so they are a waste of time.
