We agree with Julia Child: every good cook should know how to make all the proper sauces—including the often intimidating hollandaise—from scratch. But let's get real. When you're making hollandaise the traditional way, there's always the chance that the sauce will curdle. And if you've got a hungry crowd waiting for brunch, this may be the right occasion for a legitimate shortcut. We found her method, which she says is "within the capabilities of an 8-year-old child", to be nearly failproof and the resulting sauce just a little lighter. This shortcut is adapted from Julia Child's Mastering the Art of French Cooking, Volume I (Knopf, 1961).
