Soak sultanas in 100 ml apple juice for about 20 minutes. Wash apples, dab dry, quarter and core them. Weigh 150 g fruit flesh and dice. Heat butter in a saucepan. Steam diced apples in it for 3-4 minutes, take them out and let them drip off
Drain the sultanas. Knead the sourdough in the package a little with your hands. Knead sourdough, flour, yeast, salt, 150 ml apple juice and 150-175 ml lukewarm water with the dough hook of the hand mixer for about 5 minutes to a slightly moist, smooth dough. Finally knead in apple pieces and sultanas
Wrap the dough bowl with the dough completely with aluminium foil. Leave to rise in a warm place for about 1 hour. Tip the dough onto a floured work surface, cut in half and form into 2 round loaves (each approx. 14 cm Ø) (but do not knead any more!) and place on 2 pieces of baking paper. Spread a thin layer of water on bread loaves, press them to the edge with oat flakes and sprinkle bread with them. Put breads with baking paper in 2 ovenproof pots (approx. 16 cm Ø). Shorten the baking paper if necessary
Cover the bread with the lid and let it rise for about 30 minutes, then place it on the oven rack and put it in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) on the 2nd rail from below. Pour 1 cup of water onto the bottom of the oven (or into an ovenproof mould and place it on the bottom of the oven). Close the oven immediately. Bake for 30-40 minutes. Reduce temperature (electric oven: 175 °C/ convection oven: 150 °C/ gas: level 2), remove lid, bake for another 40-50 minutes
Take out the cake. Spread the rest of the gooseberries on top and sprinkle with the syrup. Let the cake cool down, then remove from the mould. The breads are ready when they sound hollow when you knock on them. Take out the breads with the pots, take the breads with baking paper out of the pots, cover them with a tea towel and let them cool down
waiting time approx. 1 1/2 hours
