Cream 125 g fat, 75 g sugar and half of the fine orange peel. Stir in the eggs one after the other. Add milk. Mix flour and baking powder and finally stir in briefly.
Line the bottom of a springform pan (26 cmØ) with baking paper. Fill in the dough and smooth it down. Bake in the preheated oven (electric: 200°C/ gas: level 3) for 15-20 minutes. In the meantime, drain mandarins on a sieve and collect the juice.
Peel oranges so that the white skin is completely removed. Remove the fillets with a sharp knife between the parting skins. Squeeze the remaining juice out of the parting skins. Pour the mandarins and orange juice together.
Prick the hot cake several times with a wooden skewer and soak with 2-3 tablespoons of juice. Remove the cake from the mould and let it cool down. Fill the remaining juice with orange juice from the bottle to 450 ml.
Take off some juice and stir with the pudding powder until smooth. Boil up the rest of the juice, fine orange peel and 2 tablespoons of sugar. Stir in the pudding powder, bring to the boil again briefly, fold in the orange and tangerine fillets.
Place a springform pan rim or cake ring around the base and spread the orange compote on top. Let it cool down. In the meantime, caramelise 1 heaped tablespoon of sugar in a pan until golden brown. Add the rest of the fat and almonds, turn them over and place them on a piece of oiled aluminium foil, one by one if possible.
Let it cool down. Whip cream and remaining sugar until stiff and put into a piping bag with star-shaped spout. Decorate the cake just before serving with cream bows and caramelized almonds.
