Cheese Soufflés

If drama is important, the soufflé mixture should fill to the rim of the dish, and you will need to fit an aluminum foil collar, also buttered and floured or dusted with cheese, around the dish to prevent the expanding and still-liquid mass from spilling over the sides. Making a soufflé collar is a bit of a nuisance and can be avoided if you fill the soufflé dish no more than three-fourths full.
