My favorite burger for the past 30+ years is made up the road on a griddle in the back of a country store / gas station in Sunshine, Maryland. Best burgers east of the Mississippi.
That is, up until now.
They cook half pound burgers and use fresh ground chuck with toasted Burger King Whopper buns. Whopper buns! They are perfect for half pound burgers because they're wide enough for an 8 oz patty and they're narrow enough to get your mouth around them. You can't get them retail, but they'll sell them to you for 75¢.
I've been trying to perfect my own burger to be at least equal with the "Sunshine Burger" for about fifteen years. Got close but never hit it until last summer - finally.
It's a long story but the gist of it is, for one burger, light a medium fire (say 15 briquets) in your Weber kettle, add your favorite smoke wood chips as you wish, then take your desired amount of ground chuck (4, 6, 8 ounces) and shred it with a fork so that it's extremely loose. Place the pile of extremely loose ground chuck onto an upside-down grillgrate on the Weber placed right over the hot briquets. Push the edges of the pile in with a spatula so that it somewhat resembles the round shape of the burger you want. Cook it on your Weber with an upside down grillgrate (the flat side up). Sprinkle a 50/50 mixture of Dale's Steak (liquid) seasoning and Kraft Italian dressing on top of the pile of raw extremely loose ground chuck (1-2 Tbs) as it sits on the grill grate (seasoning credit Dave at SnS). Place lid on Weber. When the burger hits around 100 F as indicated with your instant read, gently flip the burger being careful not to leave any crusty remnants which have formed on the bottom of the burger. You will find that the burger has magically become a patty! The salty seasoning causes the ground chuck remnants to adhere to each other so that they are no longer loose. Furthermore, when the seasoning makes its way through the loose burger to the surface of the grate, the maillard reaction is pronounced so that you get a nice crusty surface on the burger even in a short time with a relatively low temp. Add some more of the seasoning. Place cheese on the burger as you wish. Cover for a few minutes. Pull the burger at your favorite degree of done-ness. Place on toasted burger bun with your favorite condiments. Wrap in burger wrap. Wait two minutes. Serve. It may take a few practice runs to get it just right. But the result will be an extremely tender, juicy burger with an amplified beefy taste!
