Krupnik

A peasant winter soup across Poland, Lithuania, and Belarus dating to at least the medieval period — barley was the cheapest grain in the region before potatoes arrived, and dried mushrooms preserved the late-summer forage through winter. Confusingly, the same word krupnik also names a hot honey-spiced vodka in northeastern Poland and Lithuania; the soup and the drink share only the root krupy (groats).

The same word names two things: a barley-and-mushroom soup, and a hot honey-spiced vodka common in Lithuania and northeastern Poland — they share only the root krupy (groats). Pearl barley needs a 40-minute head start before vegetables go in; the dried borowiki soaking water gets strained into the broth, and tossing it is a common amateur mistake.

A thick gold-brown soup of pearl barley, diced root vegetables (carrot, parsley root, celeriac), potato cubes, and dried wild mushrooms in a meat broth — usually beef or smoked pork ribs. The barley releases starch as it cooks, so the broth thickens lightly on its own without flour. Served with a knob of butter melting on top and dill or marjoram.

Pearl barley needs a head start — about 40 minutes of simmering before vegetables and potato go in, otherwise the grain stays chalky in the center while everything else turns to mush. Dried mushrooms (borowiki, porcini family) are soaked first and the soaking water strained into the broth; that dark liquid is where most of the savor lives, and tossing it is a common amateur mistake.
