Tim (wayupnorth):
Please don't think I "boil" chicken. I poach it, which is a totally different kettle of boneless, skinless breasts.
Poaching involves keeping the liquid at a very low, slow, feeble bubble, not even a simmer. Poaching relaxes the fibers of the meat; boiling causes them to contract.
Poaching gives a very "plush" texture to the chicken. I only do it in good-quality chicken stock, to restore some of the flavor so much of today's chicken lacks.
The oven-roasting method was popularized by Irma Rombauer and Marion Rombauer Becker, authors of The Joy of Cooking. At the time the technique was set forth in Joy, chicken was not the pappy, cottony battery-raised "product" it is today, so you got a flavorful result. Today, I don't see it working that well unless free-range chickens are used. Not everyone can afford those, and there are huge swaths of the U.S. where they're not readily available. My city, Waterloo, IA, doesn't even have a Whole Paycheck - er, Whole Foods.
