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.

Sara Lee has just released a new line of hot dog and hamburger buns in time for the summer grilling season. The buns are made along similar lines as their best-selling Soft & Smooth bread, which contains whole grains but has the same texture and flavor as white bread. The names of the buns are a mouthful -  Sara Lee Made With Whole Grain White Hot Dog and White Hamburger Buns - but if the success of their Soft & Smooth bread is anything to go on, it is a mouthful that consumers are eager to take.

How do they make these breads? Spencer Wise is a food scientist for Sara Lee who is credited with the creation of these breads and buns. They are about 24% whole grain, made using a "white whole wheat" flour developed by ConAgra to feel softer and look similar to white flour, and contain 6 grams of whole grains per bun. Wise says that while the basics like flour, oil and yeast are important, any baker could work them out, so "the real secret recipe lies in the amount of monoglycerides, enzymes and other additives, " the combination of which allows the bread to be made successfully on an industrial scale.

A London auction house is offering part of a collection of war-time spy memorabilia owned by the late Doreen Mulot, who was a member of Britain's Special Operations during World War II. One of the most unusual pieces in the collection? A pair of aged prunes.  The now hardened fruits were originally intended to carry messages to prisoners of war. After being softened in water, the pit of the prune would be removed and a message - usually maps or escape plans - sealed in waxed paper would be inserted inside. The prunes would be re-dried and shipped out.

Mulot's great nephew is the one offering the prunes and assorted other memorabilia for sale. He described the plans as being "quite ingenious, [and] not the sort of thing you usually associate with fighting a war." This particular pair of prunes was not used during the war, but were simply kept as a souvenir of Mulot's service.

MSNBC has officially uncovered the secrets that make Iron Chef America work - and unlike the Amateur Gourmet, they don't seem to have been required to sign a nondisclosure agreement. The "secret" ingredient is chosen from a list of five possible ingredients that are given to the chefs prior to the filming of the show. While they don't generally know the actual one that will be used, the time they are given to plan certainly does not make it a surprise. To get the effect of a surprise, some scenes - including the reveal of the ingredient - are subject to multiple takes. The actually cooking time is still strictly held to 60 minutes, even though some ingredients may be simmering or nearly ready to use when the clock starts.
