Quark Cheese
Quark is a fresh, unripened cheese common in Germany, Austria, and Central and Eastern Europe, made by culturing pasteurized milk with bacteria (no rennet) and then draining off the whey. The result sits texturally between yogurt and cream cheese: smooth, spoonable, and mildly tangy, with none of the graininess of cottage cheese.
Varieties
Magerquark (nonfat) is the everyday baking and cooking version in Germany, while Sahnequark or Rahmquark (cream quark) has added cream and a richer, denser texture closer to a soft cream cheese; recipes calling simply for 'quark' usually mean the nonfat or low-fat type unless otherwise specified.
Buying tips
Look for it in German, Polish, or Eastern European grocery stores, or the specialty cheese case of larger supermarkets. Choose a tub with a fresh, tangy smell (never sour or off) and a smooth, unbroken texture with no separated liquid pooling on top.
Substitutes
Full-fat Greek yogurt — 1:1
Closest everyday match for both baking and spreads; slightly tangier than quark, so it works especially well in cheesecakes and dips.
Cottage cheese, blended smooth — 1:1
Run small-curd cottage cheese through a food processor for 1-2 minutes until completely smooth before substituting, otherwise the curds stay visible in finished dishes.
Fromage blanc — 1:1
A near-identical French fresh cheese; the best swap for German quark cheesecakes and tarts since the texture and mild tang match closely.
Cream cheese thinned with milk — 3/4 cup cream cheese plus 1/4 cup milk per 1 cup quark
Denser and richer than quark, so thin it gradually with milk until it drops off a spoon the way quark does; best for baked goods rather than light dips.
Ricotta, drained and pushed through a fine sieve — 1:1
Sweeter and slightly grainier unless well-drained and sieved first; a reasonable stand-in for baked cheesecakes but weaker in savory spreads.
Sour cream mixed with cottage cheese — equal parts, blended smooth
Approximates quark's tang and creaminess for dips and spreads; blend until no curds remain visible.
Storage
Keep quark refrigerated in its sealed container and use within about a week of opening. It separates and turns watery if frozen, so buy only what will be used soon rather than freezing extra.
How to use
Used in German cheesecake (Käsekuchen), cheese dumplings (Topfenknödel), fruit tarts, and pancake or waffle batter for extra tenderness and tang. In savory cooking, it's stirred with herbs, garlic, and radishes for a spread, used to bind fillings, or thinned with milk as a lighter alternative to sour cream in dressings.
What it pairs with
Pairs well with fresh herbs like dill and chives, sliced radishes, dark rye or pumpernickel bread, cucumber, honey, and soft summer fruit like berries or stone fruit.
Nutrition
Quark is naturally high in protein and calcium. Magerquark (the nonfat version common in Germany) has very little fat, while full-fat Sahnequark is closer in richness to a light cream cheese.
FAQ
What is quark cheese made from?
Pasteurized milk cultured with lactic acid bacteria, then gently drained of whey without using rennet, which is why it has no curds and a smooth, yogurt-like consistency.
Is quark the same as cottage cheese?
No. Cottage cheese keeps distinct curds in a looser liquid, while quark is smooth and homogenous throughout, closer in texture to a thick, spreadable yogurt.
Can quark be made at home?
Yes: gently warm milk with a small amount of buttermilk as a culture, let it sit until it thickens and separates slightly, then strain it through cheesecloth for a few hours to the desired thickness.
Why does quark sometimes turn watery in the container?
A thin layer of whey naturally separates during storage as the cheese sits; simply stir it back in or pour it off before using, it doesn't mean the cheese has spoiled.
