According to Julia Child, "the basic French dressing of France is a mixture of good wine, vinegar, oil, salt, pepper, herbs, and mustard. . . . Worcestershire, curry, cheese, and tomato flavorings are not French additions, and sugar is a heresy." Julia would have a fit if you ever served her that goopy orange stuff we call "French dressing," and you'd have a hard time finding it at your favorite Parisian bistro—it's an invention of American commercial salad dressing producers.
