Drain the cherries in a colander. Grease a baking dish with butter and sprinkle with breadcrumbs. Cut the halved bread rolls into thin slices, place in a bowl and drizzle with the milk. Preheat the oven to 200 ° top / bottom heat.
Separate the eggs and beat the egg whites with a pinch of salt to form snow. Mix the butter with the sugar until creamy, add the egg yolks one after the other and stir until fluffy. Mix in the bread first, then the cherries and snow. Pour this mixture into the baking dish, place a few flakes of butter on top and bake for 30 minutes on the middle rack.
