Wash and drain the raisins. Mix egg, milk, oil, vanillin sugar, sugar and quark. Mix flour and baking powder, add and knead to a smooth dough. Dab raisins dry.
Chop the lemon month a little finer. Knead raisins, almonds and candied lemon peel into the dough. Cut the dough in half and form into two rolls (approx. 60 cm long) with well floured hands. Twist the rolls into each other and lay them in a wreath.
Place on a baking tray lined with baking paper. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 50-60 minutes, remove from oven. Heat up the apricot jam, pass through a sieve and after about 10 minutes spread on the warm wreath.
Sprinkle with sugar crystals. Makes about 25 pieces.
