Maggie's Farm

Other than the capers and wine, we have been making a similar burger for years.

1 lb hamburger meat (we like 20% fat instead of the lean)
1 egg
1/4 cup dry bread crumbs (my wife insists on using italian bread crumbs)
1 tablespoon mustard or 1 tsp dry mustard
1 teaspoon salt
1/4 teaspoon pepper
1/2 teaspoon garlic powder
2 tablespoons ketchup

Mix everything except the meat together and get it into a paste. Then add the meat and shape into 4 patties. I cook them in a frying pan on the stove over medium heat for about 5 minutes on each side. I like mine pink in the middle, though my wife wants them grey throughout.

I serve mine on a buttered, toasted bun and topped with bacon and with melted Swiss cheese and a slice of sautéed red onion (sautéed in the bacon grease).

Beats the heck out of any store-bought burger I've tasted.
