Quark can be used in many ways. Making your own quark is very easy. The workload is only 10 minutes. The maturing of the quark takes about 2 days. The quantity is enough for 250 g. Mix 1.5% milk with butter in a plastic bowl. Close the bowl. Allow to stand for 48 hours at room temperature. Place bowl with lid on a cloth in the middle of the cold baking oven. Heat baking oven to 30° C to 35° C. Heat the milk for 90 to 120 minutes until the whey separates. Line the sieve with a cloth and place it on a bowl. Fill in the quark. The whey, which is collected when you make it yourself, can be drunk. Place in a cool place for 2 hours. Quark and whey can be kept in the refrigerator for 5 to 7 days.
