You may be calling it "quark" then? From a quick search:

"The two most common translations of tvorog are cottage cheese (common in the US) and quark (common in Germany). The process of making these different cheeses is quite similar: you take fermented, acidized or sour milk, and separate the curds from the whey. For cottage cheese, cream is added to the curds before they’re packaged, and for quark, the curds are not overly dried so the curds come out quite soft and creamy. Tvorog, on the other hand, is most often packaged as dry grainy pieces of curd."
