Defrost the blueberries, briefly wash and sort the cultivated blueberries and drain well. Halve rolls and cut into thin slices. Heat 40 g fat in a frying pan, add bread pieces and roast light brown while turning.
Put them in a bowl and pour hot milk over them. Cream the remaining fat, sugar, vanilla pulp and lemon zest. Separate the eggs. Stir in the egg yolks bit by bit. Add 75 g almonds and the soaked rolls.
Beat the egg whites until stiff and fold loosely into the mixture. Grease 4 ovenproof dishes (approx. 12 cm Ø) and sprinkle with the remaining almonds. Put half of the blueberries into the moulds. Fill with bread mixture and sprinkle with remaining fruit.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for about 15 minutes. Sprinkle with icing sugar while still hot and serve immediately.
