This recipe will fill a springform measuring 18 cm in diameter and yields about 6-8 portions.
In order to be able to whisk the egg whites, there can´t be any trace of egg yolk or grease in the bowl.
To make serving easier, place some plastic strips or baking paper on the inside of the springform ring.
It is possible to freeze the gateau for later use.
The egg yolks in this recipe are no longer raw but cooked in the pâte à bombe and safe to eat.
