Curd and fermented milk
Quark
Soft fresh curd of German and Central European kitchens, used in cheesecake, dumplings and with potatoes and linseed oil.
Quark is a fresh, unripened curd made by souring milk until it sets, then gently warming and straining it. It is soft, white and mild, between yoghurt and cottage cheese. In Germany it is eaten every day, in Poland it is twaróg and in Russia tvorog. Much of its use is in cooking and baking, from cheesecake to sweet and savoury dumplings.

Made step by step
Each drawing shows the operation for that step. Quantities and timings differ from house to house and herd to herd; this is one traditional way, in outline.
Step 1: Ferment Warm the milk and stir in lactic cultures and a drop of rennet. Step 2: Set Leave it until it sets to a soft curd. Step 3: Cook Cut and gently warm the curd so it releases whey. Step 4: Strain Strain it in cloth until thick. Step 5: Serve Beat it smooth and serve or bake. Finished Quark, by share.
Making it
Milk is soured with lactic cultures, sometimes with a little rennet, and left to set. The curd is cut, warmed slightly and strained in cloth or by machine until the whey runs off. Fat content is adjusted by adding cream back. In farmhouses, soured milk was simply hung in a cloth bag overnight.
In the kitchen
German Käsekuchen is made with quark rather than cream cheese, and Saxony's Eierschecke layers it with custard. Pellkartoffeln mit Quark, boiled potatoes with herbed quark and linseed oil, is a classic of eastern Germany and the Sorbian lands. Polish pierogi ruskie mix twaróg with potato, and Russian syrniki are fried tvorog pancakes.
