Despite the surrealistic name, fried milk is, indeed, a food. In Spanish cooking, the milk in question is contained within a sweet custard, which is fried and cut into squares. It's allegedly quite delicious, but I've had yet to make it or come across it in a resturant, so I guess I'll just take their word for it.

Chinese cooking also has a recipe called "fried milk", in which the milk is part of a stir fry. This fried milk originates from the Guangdong region. Guandong cooking often utilizes frying and milk in its recipes, so the cognitive leap required was probably much shorter than that involved in the creation of the first cheese. And don't even get me started on the original crazy, er, dairy farmer who decided he just had to molest the udders of a postpartum cow...

In any case, fried milk of either recipe probably tastes a lot better than "normal" foods like potted meat.
