Quark is a traditional unripened cheese in Germany, made by heating soured milk until the whey separates (the milk proteins are denatured), and then strained. It is a cheese that you can make at home. It is similar to ricotta, but is different, as ricotta is made from scalded milk. It is similar to cottage cheese, except that cottage cheese uses rennet to denature the protein. Most quarks are made from cow’s milk, this one is different in that it is made from sheep’s milk. Ewenity is a cooperative of farmers who raise sheep, they make many products, alongside just milk, from sheep’s milk, including yogurt (which my young daughter likes). This quark is quite good. I enjoy it spread on bread with a little jam, and have made other desserts from quark. The small tub cost $5, which I purchased at Riverdale Organic Farm.
