 * Original recipe
 * Serves 4

Ingredients

 * ½ cup onion, chopped
 * 2 tablespoons bottled horseradish
 * ¾ teaspoon garlic
 * ½ teaspoon sea salt
 * ¼ teaspoon freshly ground black pepper
 * 1½ pounds ground beef (option: use ground buffalo instead of ground beef)
 * 4 ounces sharp cheddar cheese, cut in ¼ inch cubes

Directions

 * 1) In a medium bowl thoroughly combine the onion, horseradish, garlic, salt and pepper.
 * 2) Add the beef and with your hands lightly bring all the ingredients together; being careful not to over work the meat.
 * 3) With dampened hands, form the meat into 4 patties of even thickness (these are fairly large patties; feel free to make 6 smaller patties if desired)
 * 4) Make a large depression in the top of the patties, about 2 inches wide.
 * 5) Place ¼ of the cheddar cheese in the depression (you may need to push some of the cheese lightly into the bottom) and bring the meat over the cheese, enclosing it completely.
 * 6) Place on a lined baking sheet, cover loosely with plastic wrap and refrigerate for 30 minutes.
 * 7) Meanwhile, light the grill or preheat the broiler.
 * 8) Cook the burgers for 5 minutes a side or until desired doneness.
