Mastering the Art of French Cooking... doesn't mean it has to be fancy cooking, although it can be as elaborate as you wish.
Julia ChildWhen I got to France I realized I didn't know very much about food at all. I'd never had a real cake. I'd had those cakes from cake mixes or the ones that have a lot of baking powder in them. A really good French cake doesn't have anything like that in it - it's all egg power.
