If you're making another type of souffl , for instance cheese, use butter and, for instance, a light dusting of fine bread crumbs up the side. The air that is whipped into the egg whites will expand because of the heat in the oven and souffl will rise. You're much better off preparing a smaller version that will stay puffy a little longer. This helps the batter remain light and puffy as it cooks. Spice it up.
Timing is everything.
Don't tell guests ahead of time that you're making a souffl . Most people have it within their ability to create an interesting, new interior for their home without spending a single cent. By using existing pieces of furniture and accessories in a different way, you can change the whole feel of a space. Discard anything you don't use or are tired of looking at. Having a few good pieces is far preferable than a house full of mediocre items.
