Žinčica
Hikers walking past a salaš, a Slovak shepherds' hut, are often offered a mug of žinčica, the cool, sour whey left over from making bryndza and hrudka cheese. Shepherds heat the whey until fine flakes of cheese float up, then leave it to sour, and drink it with boiled potatoes or on its own on a hot afternoon. It is thin, refreshing and tangy, a little like a light buttermilk. At the salaš it is often made from raw sheep's milk, so at home make it only from the whey of cheese made with pasteurised milk (the korbáčiky recipe gives you plenty) and vegetarian rennet. The common slip is leaving it to sour somewhere warm for too long, where it turns cheesy and harsh; a cool room and 12 hours is enough. Chef's tip: a spoonful of cultured buttermilk gives a clean, reliable sourness every time.
