The juiciest, most flavorfull burgers I ever tasted:
Place 2-5 lbs. of ground sirloin,chuck, or round (10% fat min.) in a large mixing bowl. Season with fresh ground pepper, a pinch of salt, ground white pepper, cumin, and fennel. Knead vigorously to mix in the spices. Then add finely chopped fresh onion and garlic and knead again 'til well mixed.
NOW comes the important part ..... Add equal parts of Worcestershire sauce and A-1 steak sauce and knead VIGOROUSLY. Repeat until "wet". ( by "wet",
I mean until the meat is saturated and will absorb no more!) Form the ground meat into a large ball, cover, and refrigerate for a min. of 24 hrs.
If you have done this correctly, any wors./A-1 sauce that you may have seen in the bowl WILL be gone!
Form the patties to your favorite size and let them rest @ room temp. for 1 hr. Sear over very high heat on both sides then put the cover on the grill and close the vents. Cook for another 5 mins. or til med. rare.
DO NOT FOR ANY REASON "smash" or press these burgers with a spatula while cooking!!
The end result will be a succulent burger so juicy that the juice will run down your arms! ENJOY!
