Charred Beef Medallions With Poblano Margarita Sauce - cooking recipe

Ingredients

1 tablespoon olive oil
1 tablespoon unsalted butter
1 1/2 lbs beef tenderloin, cut into 1-inch thick medallions
salt and pepper
1 small vidalia onion, cut into a medium dice
2 poblano peppers, washed, seeded and cut into a medium dice
1 tablespoon toasted and ground cumin
2 ounces gold tequila
1/4 cup lime juice
1 cup beef stock
2 ounces Grand Marnier
1 tablespoon freshly grated orange zest
1/2 cup heavy cream
1/2 teaspoon salt
1/2 teaspoon ground black pepper

Preparation

Heat the olive oil and butter in a saute pan over medium heat, season the beef medallions with salt and pepper, and add to the hot pan. Turn the heat up to high and char both sides of the beef well. To keep the beef rare to medium rare, cook quickly, turning once only after the beef has browned on the first side. Remove the beef from the pan, place on a warm platter, and set aside.
Add the diced onions and poblano peppers to the saute pan, evenly spread out and cook till wilted. Add the cumin and combine well to toast the spice again. Working carefully away from the flame, add the tequila to the pan, deglaze the pan by swirling the tequila and set back over low heat to reduce.
Add the lime juice and reduce to almost dry before adding the beef stock. Reduce the stock by half over high heat and add the Grand Marnier and fresh orange zest. Cook for 2 minutes and then add the heavy cream. Do not allow to boil but gently simmer for 2 minutes before adding the salt and pepper.
Serve the beef on a bed of sauce.
