I remember talking with the renowned food educator Anne Willan about getting people interested in cooking. Suppose you were, she said, somebody who never ever lifted up a rolling pin or a carving knife, you could start with something very basic and useful: making a vinaigrette. In retrospect Chef Jerry Pellegrino thinks she was 100% right. “I can’t think of a simpler recipe to make, and it has the benefit of being 100% usable right away, which means instant gratification.”
