Health benefits of London Broil with Soy Citrus Mayonnaise

Lemons can help to prevent oxidative damage to the body, which women with PCOS are often susceptible to. Lemons are also rich in vitamin C, flavonoids, and other antioxidants. They can potentially support the immune system and have other health benefits. Lemons also have a low glycemic index, so they should not cause a rapid rise in blood sugar when consumed in natural form.

Ingredients

3/4 cup fine-quality fermented soy sauce*
1/2 cup dry red wine
1/4 cup fresh lemon juice
1/3 cup fresh orange juice
3 tablespoons olive oil
1 bunch scallions, cut into 3-inch lengths
5 garlic cloves, smashed and peeled
1/2 teaspoon white pepper
Pinch of cayenne
2 1/2 to 3 lb top-round London broil (1 to 1 1/2 inches thick)
1 cup mayonnaise
Special equipment: an instant-read thermometer
Accompaniment: toasted or grilled country bread

Instructions

Combine soy sauce, red wine, juices, 2 tablespoons oil, scallions, garlic, white pepper, and cayenne in a 1-quart heavy-duty sealable plastic bag. Add steak and seal bag, pressing out air. Turn bag to coat steak, then marinate, chilled, turning bag occasionally, at least 4 hours.
Transfer steak to a plate and pour 2 tablespoons marinade through a fine-mesh sieve into a 1-quart heavy saucepan, discarding remainder or reserving for another use (see cooks' note, below). Bring steak to room temperature, about 30 minutes.
Heat remaining tablespoon oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then cook steak, uncovered, until underside is browned, about 5 minutes. Turn steak over, then reduce heat to moderately low and cover skillet. Continue cooking until thermometer inserted horizontally 2 inches into center of steak registers 120 °F, 10 to 12 minutes. Transfer to a cutting board and let stand at least 15 minutes (internal temperature of steak will rise to 130-135 °F for medium-rare).
While steak cooks and stands, bring marinade in saucepan to a boil, then pour into a bowl and cool completely. Whisk in mayonnaise until combined well and chill, covered, until ready to serve.
Holding knife at a 45-degree angle, cut steak across the grain into very thin slices and transfer to a platter, then drizzle with any juices accumulated on cutting board. Serve at room temperature or slightly chilled, with mayonnaise.
