Melt the butter in a large saucepan. When it starts to foam, pour in the flour all at once and mix in vigorously. Add the sugar milk. Bring to the boil, cook on a low flame for 10 minutes while stirring, until it has boiled down to a paste.
Separate egg yolks and whites. Gradually stir the egg yolks into the mixture. Add the calvados. Stir and put in a cool place.
Peel and grate the apple and add to the mixture.
Heat the oven to 200 ° C. Beat the egg whites into snow and then carefully stir into the mixture.
Butter a soufflé dish and sprinkle with sugar. Pour in the mixture and bake for 20 minutes.
Serve immediately.
For the success of the soufflé it is extremely important that the oven is not opened during the baking time, otherwise the mixture will collapse and have the consistency of a sponge cake base (own experience).
