For the absolutely best, most juicy, tender and flavorful grilled burgers you have ever sunk you chomps into, add grated frozen (freezing makes it easy to grate) salted butter to your meat. (I prefer an organic, grass fed butter, but as long as its a decent brand no off flavors will be present – salting can be a way cheap producers mask off flavors in the butter.)
Form into patties (I measure 1/3 pound burgers – about 4.8 ounces), making sure to dimple the center of the burger to prevent them turning out football shaped. (the outer edge will be thicker than the center, but cook up evenly)
Salt, pepper, season to your liking right before you grill them.
**This works best with ground beef that is leaner 90% or more. If you buy 86% lean chuck, that already has a lot of fat in it. Since I buy a steer from an organic farmer and split it with 4 friends, all my ground beef is ground 90% lean. (That way it’s flexible enough to be used in many other dishes)

This tip ensures absolutely drool worthy burgers.  Trust me.
