1.5 pounds of ground beef
Worcestershire sauce, 2 teaspoons.
1 teaspoon of quality sea salt
half a teaspoon of black pepper, ground
Half a loaf of sourdough
measuring half a cup of Secret Sauce
Thinly slice three medium Vidalia onions.
Cheddar cheese, six slices
a total of eight tablespoons of salted butter
Sauce
1/4 cup of Dijon mustard and 1/4 cup of mayonnaise
Grill sauce, measuring 1 tablespoon
30 milliliters of spicy sauce
Put the mayonnaise, mustard, barbecue sauce, and spicy sauce in a small bowl and mix well. Keep in the fridge for up to three days with a lid.
Steps to follow:
Add the Worcestershire sauce, salt, pepper, and ground beef to a big bowl. Patty the ground meat into six oval shapes.
Two tablespoons of butter, melted over medium heat in a medium cast-iron pan. Toss in one onion. About 35 minutes into cooking, stir periodically, the onion should be tender and golden brown.
Brown the patties in a large cast-iron pan over medium-high heat, about 2 minutes on each side, or until cooked through. Let the skillet cool down. Take the patties out of the pan and clean the skillet.
Layer 2–3 tablespoons of caramelized onions on top of 1 piece of bread and 1 tablespoon of Secret Sauce. Add 1 slice of cheese and 1 patty on top of that. Finish with 1 more spoonful of Secret Sauce. Finish with a second piece of bread. Proceed with the remaining patties, cheese, caramelized onions, Secret Sauce, and bread.
Sauté the onion in a pan set over medium-high heat. In a pan, melt two tablespoons of butter. Sandwiches need about 3 minutes on each side, or until golden brown and cooked through, so work in batches and turn once. As required, add the remaining butter to the skillet.
