What is
Quark is a type of fresh dairy product, common for the cuisines of German-speaking countries made by warming soured milk until the desired degree of coagulation (denaturation, curdling) of milk proteins is met, and then strained.
Organic milk is milk produced by cows that have been raised following organic farming methods. These methods include feeding the cows with organic feed and not using synthetic chemicals like pesticides or antibiotics.
