Finely chop dried fruit. Mix chopped fruits, sultanas, nuts and plum brandy. Leave to stand for at least 4 hours. In the meantime warm the milk lukewarm. Dissolve yeast and honey in it while stirring.
Let yeast milk go for about 20 minutes.
Cut the vanilla pod lengthwise and scrape out the pulp. Wash the lemon hot, rub the peel thinly. Put 500 g flour in a bowl. Add quark, yeast milk, 125 g butter in pieces, 100 g sugar, vanilla pulp, lemon rind and 1 pinch of salt.
Work everything into a smooth dough, cover and leave to rise in a warm place for about 1 hour.
Line a baking tray with baking paper. Preheat the oven (electric cooker: 175 °C/circulating air: 150 °C/gas: level 2). Knead the fruit mixture into the dough. Roll out the dough on a little flour to a rectangle (approx. 30 x 45 cm) and form a stollen (see
right). Leave to stand on the tray for about 20 minutes. Bake in a hot oven for 50-60 minutes (if the stollen gets too dark, cover with aluminium foil).
Melt 250 g butter. Alternately brush the still hot stollen with butter and dust with icing sugar. Let it cool down. Dust it again thickly with icing sugar. Wrap in aluminium foil and store for 3-4 weeks.
