For approx. 1 ½ lbs. of ground beef, usually I recommend that you get the 80% to get some fat taste (a little fat never hurt anyone ).
- Add 3 egg yolks
- ½ Red onion chopped very fine
- 2 large tablespoons of Dijon Mustard
- 1 large tablespoon of catsup
- 1 large tablespoon of Worchester sauce
Mix well and grill to your preference of done. For even more yumminess butter the buns and grill them too! Of course pile on all your favorite condiments, for the ultimate in a big, messy, gooey burger.
