GRILLED COFFEE BALSAMIC FLANK STEAK

Steps:

• In a small mixing bowl, whisk the coffee with the balsamic vinegar, coffee syrup and garlic. Set aside.
• Cut any excess fat off of the steak and place it in a large zip-lock bag -- the bag should be large enough so the steak is flat, or almost flat. Pour the marinade in the bag, making sure it coats both sides. Gently let all the air out of the bag, seal it, and place it in the refrigerator overnight and ideally for about 24 hours. (It's a good idea to put the bag in a bowl in case it leaks.)
• Remove the steak from the refrigerator about 20 minutes before you're ready to cook.
• Preheat a stove-top grill (or outdoor barbecue), and take the marinated steak out of the bag and place it on a large plate.
• Season both sides generously with salt and pepper.
• Place the steak on the grill. You should hear a sizzling sound when the meat hits the grill - if you don't, the grill isn't' hot enough, and the steak won't caramelize and form a beautiful crust. Wait for the sizzle!
• Grill the steak until it's cooked the way you like it -- for medium-rare, about 8 minutes. Turn the steak over about half way through the grilling time.
• While the steak is grilling, add the coffee syrup, balsamic vinegar and espresso powder to a small saucepan, and place it over medium heat. Once it's simmering strongly, turn the heat to low, add the butter, and swirl the pan around until the butter has completely melted and blended in. Season to taste with salt and pepper.
• Place the steak on a large plate or platter, cover with foil, and let it rest for at least 10 minutes to allow the juices settle.
• Slice the steak thinly against the grain, drizzle the glaze on top and serve.
