Super Special Patty Melt

Directions

1. Melt the butter in a medium skillet and add the onions. Toss to coat, cover the skillet and cook over low heat for 20 minutes, tossing the onions a couple times during the cooking.

2. Remove the lid from the skillet and continue to cook for another 20 minutes, tossing occasionally. Add the sugar, vinegar, and salt and pepper and toss to combine. Continue to cook, stirring occasionally, an additional 10 minutes, or until the onions are dark and jammy.

3. To make the patties, gently mix the onion, beef, ketchup, and Super Special Prime in a medium bowl. Divide the meat into equal 4 portions and press each round between 2 pieces of parchment or waxed paper until about ¼” thick (you want them roughly the same dimensions as the bread you're using.)

4. Heat the oil in a large skillet, preferably cast iron, over medium-high heat. Working in 2 batches, cook patties, pressing gently, until browned but still pink in the center, about 2 minutes per side. Transfer to a plate.

5. Use a paper towel to wipe out the skillet and reduce heat to medium. Top 4 slices of bread with cheddar, then beef patties, a pile of caramelized onions, and Swiss cheese. Close up sandwiches and spread each top with 1 tsp. mayonnaise. Place in pan, mayo-side down, and top the sandwiches with a sheet of foil.

6. Place a heavy skillet on top of the sandwiches to weigh them down, and cook until the bottom is golden brown, 2-3 minutes. Remove the weighted pan and spread the top of each sandwich with 1 tsp. mayonnaise. Flip and weight again. Cook until the other side is golden brown, and the cheese is melted, about 3 minutes.
