Makes 8 burgers
Ingredients:
2 lbs ground pork
kosher salt and pepper
8 oz brie
2 cups arugula
8 brioche buns
1 cup mayo
1 cloves garlic, minced
1 recipe rhubarb ketchup (follows)
1 recipe caramelized onions (follows)
Directions:
Place the ground pork in a bowl and add 1 teaspoon of salt and 1/4 teaspoon black pepper. Gently mix together until well combined. Form the pork mixture into 8 burger patties and place on a sheet pan or plate. Refrigerate until ready to cook.
Place the mayonnaise in a small bowl and add the minced garlic. Stir well to combine and set aside or refrigerate until ready to use.
Slice the brie into 8 long slices, and then cut them in half.
Heat a large cast-iron pan over medium high heat. Sprinkle the pork burgers with salt and pepper and place 4 burgers in a single layer in the pan. Cook on one side for 2-3 minutes, or until browned. Flip over and then plac two of the half-slices of brie on top of each burger. Cook for another 3-4 minutes or until the burgers are cooked through and the brie is melted. You may need to cover the pan with a lid to finish cooking the burger and melt the cheese. Wipe out the pan and repeat the cooking process with the remaining 4 burgers. Move the burgers to a plate while you prepare the buns.
Lightly toast your brioche buns under a broiler (keep a close eye) until golden brown. Move to a plate or cutting board. Spread the rhubarb ketchup on one side and garlic mayo on the other side. Place a large pinch of caramelized onions on the bottom bun and top with a pork burger. Top with arugula and then the top bun. Serve immediately.
