(Endometriosis occurs when endometrial tissue grows and functions outside the uterus.) Adenomyosis is a significant cause of severe pelvic pain and menstrual irregularities. It typically occurs in women who have uterine fibroids, women age 40 - 50, and women who have had children.
Identify the grain of the London broil. It is similar to wood grain and resembles small lines running throughout the steak. Start cutting the London broil into 1/8-inch strips against the grain at a 45-degree angle. This is a slight angle, which will create diagonal cuts in the steak. Continue cutting until only steak strips remain. Serve the London broil with a prepared sauce to help keep the meat moist and juicy.
Slice the tri-tip across the grain to serve as you would a London broil from a flank steak; you will need to turn the steak as you cut because the grain shifts. Use pan drippings and juices that drip as the tri-tip rests to make pan gravy or a rich red wine sauce or just serve with Dijon mustard.
