Question: what is the difference between curd and cottage cheese?
Answer: The difference lies in certain steps of production after the curd is formed. With cottage cheese, the curd is cooked and cut, the whey is drained, and the curd is washed. With quark, the curd is not cooked; the curd is not cut, but broken by agitation; the whey is drained; and the curd is not washed.
