1 tablespoon Worcestershire sauce. In a bowl mix these all together and add 1 tablespoon extra virgin olive oil to bring it all together.
Add 2 1/2 Pounds of ground chuck to a bowl. (This creates 6 patties. If you need less adjust recipe as needed!) Massage the spice mixture into the meat.
Grab a tennis sized ball of the meat. Work into a ball formation. Then flatten it into a patty by compressing it with your thumbs. This might seem like a large patty but remember that it will shrink when it is cooked! Also, make sure you evenly distribute the meat so it will cook evenly.
Once you create your patties. Take a small pinch of meat out of the center of each patty. Yes. Do it! Reserve the pinched meat.
Just take 1 tablespoon of butter and cut it into fours. Then add each piece to the middle
Add a little piece of the reserved meat back to each patty and press it down to incorporate it back into the patty.
Heat your grill to high. We brush each patty with a little olive oil on each side to ensure it will not stick.
Ok, put your burgers on the grill. Depending on the size of your patties, grill them (without touching them!!) for 6 minutes on the first side. Flip once. Cook on the other side for an additional 4-5 minutes (without touching).
Your burger should register at 160 degrees F.
Take them off the grill and allow them to rest for 4-5 minutes (this ensures the juices will distribute throughout the meat).
