In a bowl or large resealable plastic bag, combine balsamic vinegar, garlic, rosemary, olive oil, and peppercorns; place steaks in the plastic bag or covered dish. Refrigerate 3 to 4 hours or overnight.
Prepare Cabernet Sauce; set aside.
Remove steaks from refrigeration 1 hour before cooking and wipe excess marinade off the steaks. When you are ready to grill, preheat barbecue grill. Place steaks onto hot grill and grill to the desired degree of doneness, about 3 to 4 minutes on each side for medium rare. Your steak is done when the internal temperature registers 120 to 130 degrees F. on your instant-read meat thermometer:
Rare - 120 degrees F
Medium - 130 degrees F
What constitutes rare and medium-rare cooked meat? To satisfy government home economists, the Beef Council says rare beef means an internal temperature of 140 degrees F. Well, that is ok if you like well-done and dry meat. If you like moist, rosy meat (like I do), rare begins when the internal temperature registers 120 degrees F. and starts to become medium rare at 125 or 130 degrees F. To cook your meat properly, you must purchase and use a good instant-read digital meat thermometer.
When the steaks are crusty-charred and done to your liking, remove from the grill and let sit 15 minutes before serving (meat temperature will rise 5 to 10 degrees after it is removed from the oven).
Pour any juices from the steaks into the prepared Cabernet Sauce; spoon the sauce over and around the steaks on individual serving plates. Sprinkle with chive batons and serve immediately.
Makes 6 servings.
In a heavy-bottomed pot, cook the onions, carrots, and celery in olive oil over medium heat until well browned. Add the garlic, bay leaves, and tomato paste; cook 1 minute, stirring. Add the vinegars and wine, bring to a boil, and simmer until reduced by two-thirds. Add the veal or chicken stock, bring to a boil, and simmer, skimming occasionally, until reduced by two-thirds. Strain through a fine-mesh strainer. Cool and refrigerate if not using immediately.
Return the sauce to the heat and simmer until it lightly coats the back of a spoon. Season with salt and pepper and keep warm.
