Tilsiter

Tilsit stood on the Memel River in East Prussia, a German-speaking town with deep Baltic roots, and in 1807 it hosted the most famous peace conference of the Napoleonic era. Napoleon and Tsar Alexander I signed their treaty there on a raft in the middle of the river. The town's greater contribution to world cuisine came later, in the middle of the 19th century, when Swiss dairy farmers resettled in East Prussia began experimenting with local milk and alpine cheesemaking methods. By the 1860s the cheese they produced was being sold at regional markets under the name of its home town.

The Tilsiter that emerged from those East Prussian dairies was a semi-hard washed-rind cheese with a firm yellow paste and small, irregular holes throughout. The washed-rind technique, in which the cheese is rubbed with brine during aging, produces a pungent rind and a milder, slightly tangy interior. Swiss cheesemakers in East Prussia adapted it to local conditions: longer aging, a firmer press, and the brackish Memel water that gave the brine a mineral character no alpine spring could replicate. The result was distinctly East Prussian even if its technique was Swiss.

In 1945, the Red Army captured Tilsit and the city was transferred to the Soviet Union as part of the postwar territorial settlement. The Germans were expelled, the Swiss dairymen were long gone, and the town was renamed Sovetsk. The cheese, however, kept its old name in West Germany and Switzerland, where production had already taken root before the war. Swiss cheesemakers formalized Tilsiter as a category in their own right, producing both a plain-rind and a caraway-seeded version that became standards of Swiss supermarket cheese counters by the 1970s.

The modern Swiss Tilsiter is a protected designation in Switzerland and a workhorse of German-speaking dairy counters, but it is barely known outside central Europe. The name still carries Sovetsk in it, a ghost address from a town that no longer exists as it was. Visitors to Sovetsk today find a small Russian city with Soviet-era apartment blocks and one small museum that mentions the famous 1807 treaty. There is no cheese museum, though perhaps there should be.
