When I was a kid, Carnation ran TV commercials where they suggested one add evaporated milk to meat loaf. This hamburger recipe promotes the same principle.
Here's the retro recipe for Carnation Bar-B-Burgers.
1/3 cup (small can) undiluted Carnation Evaporated Milk
1 1/2 pounds ground beef
1/2 cup fine cracker crumbs
1 1/2 teaspoon salt
1/4 teaspoon pepper
1 teaspoon dry mustard
1/4 cup finely chopped onion
1/2 cup finely shopped green pepper
Blend all ingredients until well mixed. Form into 6 patties and broil 5 - 7 minutes on each side (or to your family's taste).
