Hamburgers With Mustard Butter image

Molly O'Neill introduced this hamburger to The Times in 1994, a firm patty wrapped around a pat of sharp mustard butter that melts throughout the meat. It is a noble sandwich that elevates a regular burger into the realms of the sublime.

Ingredients

2 tablespoons unsalted butter, softened
2 teaspoons Dijon mustard
2 plum tomatoes, diced
1/2 red onion, diced
1 1/2 pounds ground beef
4 romaine lettuce leaves
4 hamburger buns
1 1/2 teaspoons salt
Freshly ground pepper to taste

Steps:

Combine butter and mustard until smooth. Chill until semifirm. Toss together tomatoes and onion.
Start a charcoal grill. Divide the beef and mustard butter into 4 four equal portions. Press butter into the center of each piece of beef and form a ball around it. Gently flatten into a patty. Grill to desired doneness.
Place a lettuce leaf on the bottom half of each bun and top with a patty. Season the meat with the salt and pepper. Top with the tomato mixture and bun tops. Serve immediately.
