Heat the sultanas and 125 ml of juice in a covered saucepan. Remove from the heat and leave to stand overnight in a closed pot. Put almond kernels in a pot, add water so that the almonds are completely covered.
Bring to the boil, simmer for about 1 minute, pour into a sieve, drain and press out of the skin immediately.
Whisk butter, sugar, vanilla sugar and salt with the whisk of the hand mixer until foamy. Add the eggs one by one and stir in. Add 50 g jam, lemon and orange peel, stir in briefly.
Mix flour, ground almonds, spices and baking powder. Stir briefly into the dough. Add sultanas and berry mixture and fold into the dough. Put the dough into a springform pan (26 cm Ø) lined with baking paper, smooth it down and bake in a preheated oven (electric cooker: 160 °C/ convection oven: 125 °C/ gas: see
manufacturer) on the second rack from below for approx. 25 minutes.
In the meantime, cut the skinned almonds lengthwise in half. Take the cake out of the oven, place it on a cake rack and cover it with the almond kernels in a tightly wreathed pattern. Put back into the hot oven and continue baking at the same temperature for about 1 hour.
Just before the end of the baking time, heat 150 g jam and 75 ml orange juice in a small pot. Pass through a fine sieve. Take the cake out of the oven, place it on a grid, spread the orange-apricot glaze on the cake immediately and let it cool down.
