Got this one right out of "Barbecue Secrets" by Ron Shewchuck. Makes a damn good burger IMO. I'll try to condense it some to save some typing....especially since I make a lot of typos after a couple of drinks.
2 lbs Ground Beef
1/2 tsp freshly grated nutmeg
4 1/2 inch disks of frozen Mediterranean Herbed Butter (to follow)
1 Tbsp Dijon Mustard
Champsionship BBQ Rub (below)
4 Buns
exta softened herbed butter (below) for the buns
granulated garlic
1/2 cup chevre (a creamy white french-style goat chees) at room temp
2 large roasted red bell peppers
Carmelized Onions (below)
Combine the beef and nutmeg. Mix together lightly with your hands, don't over work it. Split into 4 equal portions and roll into balls. Poke your thumb in the middle of each ball to create a hole and insert a frozen disk of herbed butter. Encase the butter in the burger as you shape it about 3/4 inch thick, ensuring that there are no openings where molten butter could run out.
Coat the patties lightly with mustard and sprinkle them with a light coating of the rub.
Cook the burgers. Remove them from the grill and tent with foil and let rest for 4 to 5 minutes. In the meantime, coat the buns with the softened herb butter, sprinkle with a little granulated garlic and toast for 30 to 60 seconds on the grill.
Dress the burgers with a slather of goat cheese, a piece of roasted red pepper, and a dollop of caramelized onion.
Rub
1 C sugar
1/4 C celery salt
1/4 C garlic salt
1/4 C onion salt
1/4 C Seasoning salt
1/3 C Chili Powder
1/3 C Black Pepper
1/3 C Paprika
Herbed Butter
1 lb unsalted butter
4 Tbs Italian Parsley
4 Tbs dill, basil or mint (or any combo of fresh herbs)
Kosher salt to taste
Carmelized Onions
2 Tbs butter or olive oil
4 medium onions, peeled and sliced into rings
1/2 tsp kosher salt
1 tsp sugar
1/2 tsp ground cinnamon
pinch cayenne
Heat the butter/oil, add the onions and salt and suate until soft (5 minutes) as the sugar, cinnamon, and cayenne and continue to saute until the onions are shiny and brown (about 15 minutes).
Yeah, it is a lot of work and hassle for a burger, but damn they are good.
Quite often we don't have the cheese, don't feel like making the herbed butter, and are out of onions. LOL The rub on the meat with regular butter inside and plain old cheddar on top still makes a dang good burger.
