This recipe calls for Beau Monde seasoning. Beau Monde is a mellow beefy flavor with broad tones of celery, onion and garlic. Widely sought for use in party dips and Bloody Marys. Marvelous on salads, green vegetables, or pot roast. It can be hard to find. Spice Island is one brand. There seems to be a lot of recipe for making Beau Monde seasoning with a lot of ingredients in them, I'm sure they're all good so if you can't find the seasoning in the grocery store make your own or just omit altogether.
