1⁄4 l Warm milk lukewarm. Crumble yeast into it and dissolve. Put 1 kg of flour in a large bowl, press a depression in the middle. Pour in the yeast milk and mix it with some flour from the rim to a pre-dough.
Cover and leave to rest in a warm place for about 30 minutes.
Wash the raisins, drain and sprinkle with rum. Warm 5 tablespoons of milk. Coarsely chop the almonds and add them to the warm milk. Put both aside.
Finely chop the candied lemon peel and candied orange peel. Add almonds together with milk, 200 g sugar, salt, lemon zest, flavour and 500 g butter in flakes to the pre-dough. Knead everything to a smooth dough (best with a food processor).
Lastly, knead the raisins with your hands. Cover the dough and let it rise in a warm place for about 2 hours.
Knead the dough again and possibly divide it 1⁄5 Dough for the stollen cake. Halve the stollen dough and form into 2 oval loaves. Place them side by side on a baking tray lined with baking paper and cut lengthwise.
Bake in a preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for about 1 hour (or see tip).
Melt 250 g butter. Spread the stollen immediately with approx. 1⁄3 butter and sprinkle with 100 g sugar. Repeat the process with approx. 1⁄3 butter and 100 g sugar. Spread the rest of the butter on top and dust thickly with icing sugar.
Let it cool down. Before consumption, allow to soak in a cool, dry place for at least 2 weeks.
