The competitors on Top Chef seem to endlessly complain when they have to work with an ingredient that they didn't make from scratch, repeating ad nauseum that they feel such things - namely, processed foods - are far beneath them. But using commercial ingredients isn't beneath all chefs, not even ones like Jean-Georges Vongerichten and David Bouley. Vongerichten serves his Two-Flavored Stir-Fried Shrimp in a sauce of Hellmann's Mayo and condensed milk. Bouley uses Heinz Ketchup in several sauces, including the one served with his Braised Hawaiian Yellowtail appetizer. Other secret ingredients in chefs' pantries include Gravy Master, Kraft Singles, canned creamed corn and Dr. Pepper.
How are high-end, starred chefs getting away with using ingredients that you could find at a convenience store? The answer is that they don't advertise it the same way that they highlight grass-fed beef and organic tomatoes on their menus.
