Caramelise 100 g sugar in a pan until golden. Pour evenly into a slightly greased ovenproof dish (approx. 22 x 22 cm). Leave to cool.
Cut off the crust all around the bread. Cut the bread into 12 slices and place them in about 3 layers in the mould.
Warm the milk lukewarm. Score the vanilla pod lengthwise and scrape out the pulp. Wash the lemon hot, dab dry and finely grate the peel. Add both to the milk with 100 g sugar. Pour evenly over the slices of bread and leave to soak in for approx. 10 minutes.
Whisk eggs and 75 g sugar. Pour over the bread and let it stand for about 30 minutes.
Peel, quarter and core the apples. Cut the apple quarters into slices and place them on the bread in a fan shape. Mix 1 tablespoon of sugar and cinnamon and sprinkle the apples with it.
Bake the bread pudding in a preheated oven (electric oven: 175 °C/circulating air: 150 °C/gas: level 2) for approx. 40 minutes. Take out and dust with icing sugar. Dulce de Leche is delicious with it (see right).
Drinks tip: Coffee with milk.
