Hamburgers

Combine the water and Worcestershire, and, using your hands, blend into the beef until evenly distributed.

Divide the meat into eight equal parts, roll into balls (but do not overwork the meat because it can toughen your burgers), and flatten into discs about 1/2 inch thick and 4-1/2 to 5 inches across. Chill for at least 1 hour or up to 1 day.

Place a cast iron griddle on one area of a well-oiled charcoal or gas grill. Preheat all areas to high.

Combine the seasoning blend ingredients.

Combine all of the basting butter ingredients over medium heat and pour into a baking dish or disposable aluminum pan.

Swab the oil on the griddle, add the onions, close the lid and cook until golden, about 3 minutes. Flip, close the lid and cook for another 3 minutes. (If you have a grill press or a fire brick wrapped in heavy-duty aluminum foil, it is ideal to keep on hand to keep the rings from lifting up and also maximizes the caramelization.)

Brush with the 2 tablespoons of butter, sprinkle with the pepper flakes and continue to cook until caramelized and tender. Some breakage is OK, particularly if not using the grill press, but it is better if they stay together.

Transfer the onions to a bowl and cover to keep warm while the burgers cook. Do not clean the griddle.

Season both sides of the burgers using about half of the blend.

It is preferable to move the burgers to a clean area of the griddle and grate every time they are flipped. Depending on the griddle and grill size, they will need to be cooked in batches to ensure there is a clean portion of the griddle and grill to flip to. (It is best to read the full step below first before continuing.)

Place four burgers on the exposed grate, keeping the other half clean to flip to. Close the lid and cook until the meat easily separates from the grate and is well marked, about 2 minutes. Flip the burgers to the clean section, close the lid, and cook without moving for 2 minutes.

Season the burgers with some of the remaining seasoning blend.

Transfer the burgers to the griddle, brush with butter using the herb bundle, and continue to cook, flipping once, until the desired doneness.

Cook 2 to 3 minutes for rare, about 4 minutes for medium, and 5 to 6 for well done.

Once the first four burgers are on the griddle, scrape the grates, re-oil, and repeat the grilling process. As the burgers reach desired doneness on the griddle, transfer to a sheet pan and cover with foil while the other burgers cook.

When all burgers have been cooked, turn off the heat on all areas of the grill. Place the burgers and the buns on the grate. Brush the buns with butter, if desired, and top burgers with the cheese, if using. Close the lid for 1 to 2 minutes to melt the cheese and toast the buns.

Serve burgers and cheeseburgers topped with the onions on a toasted bun.
