That would be some loud cheer! But an even greater curiosity is that, while you can find quite a few descriptions of this tradition on the Internet (mostly in Polish, though), they all sound quite similar (usually not longer than one or two sentences) and, what's more, none of them cites any sources of this information. Surely, if it's really a time-honoured tradition it is claimed to be, then it must have been mentioned in some old books, right?
However, I've been unable to find any mention of the "bigos with a cheer" in pre-Internet sources. You could say, of course, that I could have asked some of those people who wrote or talked about it. Well, I tried, but to no avail. It would turn out that either the source has escaped that person's memory or that it's simply a fact so obvious that no citations are necessary. Besides, you can find information about bigos with a cheer everywhere, I've been told; just grab any 19th-century cookbook that comes at to hand. Well, it is true that old recipes do mention a method of cooking where the pot is sealed with dough. Ćwierczakiewiczowa advises to cook the "English meatloaf" in such a way,<ref>{{Cyt
