Heat the oil to 170 ° C and add the mixture with two tablespoons or an ice cream scoop. Bake the quark balls until light brown. They often spin on their own and get through quickly, so it is better not to let them get too dark. Then roll in sugar.
They taste like at the bakery. After tinkering several times, this is now my favorite recipe and that of my children. They are totally airy and light and not dry.
