While the gelatin swells and the cakes are soaked, let’s prepare the most delicate creamy souffle. To do this, whisk the yolks with sugar until a thick white mass forms, pour in the milk, pour in the flour and put it in a water bath, stirring occasionally. The mass will increase slightly in volume. As soon as the first bubbles begin to appear, stir and remove from the heat. Cover with a film in the “contact” mode and put it to cool in cold water, stirring occasionally.
