Warm the milk lukewarm. Crumble yeast, mix with 1 teaspoon sugar and 5 tablespoons milk. Cover and leave to rise in a warm place for about 10 minutes
Place fat, salt, flour, egg, 50 g sugar, remaining milk and vanillin sugar in a bowl. Add yeast milk and knead with the dough hooks of the hand mixer to a smooth dough. Cover and leave to rise in a warm place for about 30 minutes
Cut the mango into pieces. Bring mango and apple juice to the boil, put aside and leave to stand for about 10 minutes. Pour mango into a sieve and drain well. Chop nuts and candied lemon peel finely. Mix nuts, mango, lemon peel and jam
Knead the dough again and roll out into a rectangle (approx. 45 x 70 cm) on a floured work surface. Divide the rectangle into three parts lengthwise. Also divide the filling into three. Place the filling on one long side of each dough rectangle and roll up. Weave the dough rolls into a plait, make sure that the "dough seam" always points downwards and place on a baking tray lined with baking paper. Form the plait into a wreath and braid the ends together and press them firmly. Whisk the egg yolk and cream and brush the wreath with it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 30-35 minutes, if necessary cover the last 10-15 minutes with aluminium foil
Let the wreath cool down on a cake rack. Dust with icing sugar and serve warm or cold
