I never buy top sirloin, because I don't find it to be the most flavorful of steaks, but it was on sale at Safeway and I figured it was worth a try. I looked for a recipe in epicurious.com, and found this one for Grilled Steak Verciano. I made it last night and it was *very good*. It imparted the meat with a strong flavor (lots of it from wine, so don't make it unless you like red wine), and both Mike and I loved it.
I didn't get the grill hot enough before I cooked the steaks, so 4 minutes on each side led to a very rare steak. Next time I'll get it hotter, but I'll probably do 5 minutes on each side anyway.
Grilled steak with wine-soy sauce marinade
1/2 cup red wine
2 Tbsp. soy sauce
1 Tbsp. Worcestershire sauce
2 tsp. dried rosemary
2 large garlic cloves, chopped
1/2 tsp. salt
1 1/2-pounds top sirloin steaks
Mix the red wine with the soy sauce, Worcestershire sauce, rosemary, garlic and salt. Add the steaks and cover well on both sides. Marinade in the refrigerator for 6 hours, turning half way through.
Heat a grill to medium-high. Grill the steaks until done, about 4 minutes on each side for medium-rare.
