Having parents with a Polish background and being brought up on a farm, I grew up on it. Has many health benefits, but also many people will find a reason to avoid it. Even today in Europe it is commonly available.
I would be interested in your feedback, especially regarding taste. As a kid I did not mind it. I loved all the cheeses and yoghurts we made from it though.
Good to see it is available, even if only for "cosmetic" purposes.
