If it was mucus from a tuberculosis affected Swallow, the Chinese would buy the whole production!
Even if I have sounded negative to the American cheese products, I have to confess that the various Blue cheeses are good. Not as good maybe as a Roquefort, but just as good as any European Blue Cheese.
Some are called Amish Blue Cheese and similar.
Made by Amish? I do not know.
Swedish, Danish, English, American = same good. I eat a lot of Blue Cheese, from many countries. Usually I let them mature for a couple of weeks in the fridge. All turn perfectly delicious.
We get several sorts of Stilton here before X-mas, in beautiful, useful, ceramic jars. Badly unmatured, so the wax layer has to be removed and the jars stored in the warmest part of the fridge or the wine room for at least 2 weeks before they taste good.
