Real Hamburgers

Ingredients

• 2 pounds ground chuck
• 1 pound ground sirloin
• 3 tablespoons steak sauce (recommended: Crosse & Blackwell)
• 6 extra-large egg yolks
• 1 1/2 teaspoons kosher salt
• 3/4 teaspoon freshly ground black pepper
• 4 tablespoons cold unsalted butter
• 12 hamburger buns

Directions

Carefully mix the meats, steak sauce, egg yolks, salt, and pepper with the tines of a fork, but do not mash it. Lightly form each hamburger and lightly press into a patty shape. Make an indentation and put a thin slice of butter inside each hamburger, making sure the butter is entirely encased in the meat.

Heat a grill, broiler, or saute pan and cook the hamburgers for 3 to 5 minutes on each side until almost done. Remove to a plate and cover with aluminum foil. Allow the hamburgers to rest for 5 minutes and serve immediately on buns.
