Grilled Flank Steak with Tempranillo Bordelaise Sauce

This recipe I recently tried and thought it was really good. You need to follow the instructions exactly. If you cook the flank steak too long it will be tough, and if you do not let the sauce reduce down enough it will be watery.

Ingredients:
1/4 cup Extra Virgin Olive Oil
1 tsp. Fresh Garlic
1/2 cup Shallots, minced
1 ea. Small Onion, peeled and chopped
1 ea. Small Carrot, peeled and chopped
1 ea. Celery Stalk, chopped
1/2 btl. Tempranillo Wine
1qt. Beef Stock
1 bunch Fresh Thyme
2-3 lbs. Flank Steak
To Taste Salt & Pepper

Sauce Procedure:
In a sauce pan, heat olive oil and saute the garlic, shallots, onion, carrot, and celery until the vegetables start to brown. Add the wine and allow to reduce until almost dry, about 15 minutes. Then add beef stock. Reduce and simmer 20-30 minutes. Next add thyme and simmer for 5 more minutes. Remove sauce from heat and strain.

Flank Steak Procedure:
Trim flank steak of muscle and excess fat if needed. Season both sides of flank steak with kosher salt and pepper. Grill over medium high heat for approximately 3-4 minutes per turn. Grill flank steak on both sides, forming diamond marks. When medium rare (120), remove from heat and allow to sit for 3-4 minutes (this makes steak more tender).

To Serve:
Warm sauce over medium heat. When warm, whisk in 4tbs of chilled butter. Whisk to incorporate butter. Thinly slice the flank steak and drizzle sauce over the steak. Serve immediately and enjoy!

My notes for this recipe:
**Do not overcook meat, 3-4 minutes is all that is needed per side.
**I added mushrooms to the sauce because I love mushrooms and thought the mushrooms were fantastic after they simmered in the wine sauce.
**I did not strain the sauce when it was finished because I wanted all the garlic and shallots and the mushrooms still in the sauce when I ate it.
**I did add a little cornstarch to the sauce after it reduced down because I wanted it to be a little thicker.
**It does make a lot, cut the recipe in half if you do not like leftovers.
