I insist my family eat the first Tavern as traditionally made, I try to turn a blind eye when I see them make a second one for themselves and use catsup...
1 pound or so of ground chuck (leaner beef an even ground turkey is ok too)
about half a container of bay leaves (a lot of them is best)
dill pickle chips
The proper way to make a Tavern is to put lots of mustard on both sides of the bun, and put dill pickle chips on one side.
Using a slotted spoon, dip out a scoop of the meat, pull out any bay leaves and put them back into the pot. Drain the meat really well, I press it against the side of the pot. Carefully transfer the meat to the bottom bun. I put the bun up to the filled spoon and turn it over, making a well formed mound in the middle of the bun. Flip the top on and eat - over a plate. It is messy!
