Tilsit cheese is a semi-hard light yellow cheese. Tilsit was created in the mid-19th century by Dutch settlers in Prussia, who set out to make Gouda cheese. The same ingredients were not available and the cheese became contaminated by molds, yeasts, and bacteria in the humid climate. The result was a cheese which was more intense and full flavored. The settlers named the cheese after Tilsit, the Prussian town they had settled in.
Tilsit has a medium-firm texture with irregular eyes or cracks. Commercially produced Tilsit is made from pasteurized cow's milk, ranges from 30 to 50 percent milk fat and has a dark yellow rind.
