Solyanka

A 16th-century tavern soup originally called селянка (selyanka, "villager's soup") — designed to use up scraps of cured meat that accumulated in inn kitchens. Renamed solyanka (from соль, sol, "salt") by the 18th century as the sour-salty profile became its identifier. A Russian hangover soup as much as a meal — the acid and salt were considered restorative the morning after.

A 16th-century tavern soup originally called селянка (selyanka, villager's soup), built to use up scraps of cured meat. The pickle brine (rassol) — not the pickles themselves — is the load-bearing seasoning, about half a cup per liter.

A sour, salty, dense soup — the broth dark from tomato paste and pickle brine, packed with three or four cured meats sliced into the pot (smoked sausage, ham, salami, often boiled tongue), plus pickled cucumber, capers, olives, lemon slice, fresh dill. The fish version (rybnaya solyanka) substitutes salmon, sturgeon, and salt herring. Served with a slice of lemon floating on top. Tastes assertively sour at first sip — that's correct.

The pickle brine (рассол, rassol), not just the pickles themselves, goes into the pot — about half a cup per liter of soup. This is the load-bearing seasoning; it provides the lactic acid, salt, and dill notes that tie the assorted meats together. Cooks who use only the pickle and not the brine end up with flat solyanka, which they then over-salt to compensate, and the soup goes harsh.
