London Broil that's been marinated overnight.
but...i've read where marinating more than
one hour is wasted time.
quote:
Contrary to popular belief, marinades do most of their work on the surface of meat or just below. Some ingredients in a marinade do penetrate the meat—but only by a few millimeters (and oil-soluble herbs and spices in the mix merely add flavor to the exterior). To prove the point, we soaked beef short ribs in red wine for intervals from one hour to 18, then measured the band of purple created by the wine. Our finding? Even after 18 hours of soaking, the wine penetrated less than 1 millimeter. Additional testing with marinated boneless chicken breasts confirmed that the flavors of other kinds of soaking liquids do not penetrate to the center of the meat.
