Put 400 g flour in a bowl, make a depression in the middle and crumble yeast into it. Warm 50 ml milk lukewarm. Add 1 tbsp. sugar to the yeast. Mix with some flour from the rim. Cover the dough and let it rise in a warm place for about 15 minutes. Meanwhile melt 100 g butter and add 50 ml cold milk. Add lukewarm fat-milk mixture, 75 g sugar, egg, vanillin sugar and 1 pinch of salt to the pre-dough. Knead to a smooth dough with the dough hooks of the hand mixer. Cover and leave to rise in a warm place for about 45 minutes
Wash the cherries, drain well, remove the stalks and pit. Put 50 g Amarettini in a freezer bag and crush them finely. Coarsely grate marzipan. Mix cherries, amarettini and marzipan. Briefly knead the yeast dough and roll out into a long rectangle (approx. 22 x 70 cm) on a floured work surface. Spread the cherry filling on the dough so that an approx. 3 cm wide edge remains free on the lower long side and a 3-4 cm wide edge on the upper long side. First beat the lower edge of the dough over the filling, then roll up the dough sheet. Brush the seam edge lightly with water if necessary and press down well
Place the roll in a greased springform pan with breadcrumbs and a tube bottom insert (26 cm Ø) and press the two ends firmly together. Allow the wreath to rise again for approx. 30 minutes
