The October 2012 Better Homes & Gardens issue has a whole spread on cooking with beer, including a recipe they recommend making with Old No. 38 Stout!

Here’s what they say about their recipe for Stout-Soaked Porterhouse with Beer Butter:

“Marinating the porterhouse steak in stout beer infuses it with bold coffeelike flavor, while our tarragon-and-stout butter adds a perfectly savory topper. Use your extra butter over hot vegetables.”

Stout-Soaked Porterhouse with Beer Butter

Makes: 2 to 3 servings
Prep 35 mins
Marinate 4 hrs
Broil 12 mins
Stand 5 mins

1    Porterhouse steak, 1-inch thick (about 1¼ lb.)
1    12 ounce bottle stout beer (Guiness)
1    tablespoon Dijon-style mustard
1    tablespoon Worcestershire sauce
2    teaspoons dried tarragon, crushed
½  teaspoon salt
½  teaspoon ground black pepper
1    shallot, finely chopped
2    teaspoons olive oil
½  cup butter, softened

Directions

1. Place steak in a self-sealing plastic bag set in a shallow dish. Set aside 2 tablespoons beer; in a small bowl combine remaining beer, mustard, Worcestershire, 1 teaspoon of the tarragon, the salt, and pepper. Pour beer mixture over steak in bag. Marinate in the refrigerator for 4 to 6 hours, turning occasionally.
2. Meanwhile, in a small skillet over medium heat, cook shallot in hot oil 5 minutes or until tender. Stir in reserved 2 tablespoons beer. Remove from heat. Cool 10 minutes. In a small bowl combine softened butter, shallot mixture, and remaining 1 teaspoon tarragon. Transfer to waxed paper, shape into a log. Wrap and freeze.
3. Preheat broiler. Drain steak; reserve marinade. Season steak with additional salt and pepper. Place steak on the unheated rack of a broiler pan. Broil 3 to 4 inches from heat to desired doneness, turning once, broiling 12 to 15 minutes for medium rare (145 degrees F) or 15 to 20 minutes for medium (160 degrees F). Transfer to platter. Tent with foil and let stand 5 minutes.
4. Place reserved marinade in a small saucepan. Bring to boiling. Reduce heat to medium and simmer, uncovered, 15 minutes (Do not overcook; marinade can become bitter).
5. To serve, slice steak into portions. Drizzle with some of the marinade reduction, and top each with a slice of frozen butter.

Makes 2 to 3 servings.
