GRILLED MARINATED FLANK STEAK

3/4 cup red wine
2 medium garlic cloves, minced
2 tbls. olive oil
1 tbl. fresh lemon juice
2 tbls. fresh orange juice
1 tsp. orange zest
1 tsp. lemon zest
1 tsp. soy sauce
1/4 tsp. salt
1/4 tsp. black pepper
1/2 tsp. curry powder (optional)
1 (2-lb.) flank steak

Combine all ingredients except flank steak in a medium mixing bowl and whisk until well combined. Taste for seasoning. Flatten out the flank steak in a large, shallow, non-aluminum dish or large plastic bag. Pour the marinade over and marinate 2 to 4 hours in the refrigerator. Prepare grill for medium-heat grilling. Remove steak from the marinade and grill 3 inches from the flame, 5 to 7 minutes per side for medium-rare. Place on a carving platter and slice thinly against the grain. Serve immediately. Serves 4 to 6.
