Totally Authentic French Onion Soup – No matter what French people say.
Totally authentic, as long as you ignore what many French people say about the base, that is. The majority of French (and other) chefs will gasp a collective “Mon Dieu” and insist on “de bouillon de bœuf”. Beef stock to you and me. What do they know? I know best. I used chicken stock and my reasoning is pretty sound.
