MUSTARD ON A BURGER RECIPES

Steps:

• Heat a griddle or large cast-iron skillet over medium heat for at least 10 minutes. Meanwhile, combine the mayonnaise, mustard and pickle brine in a small bowl. Combine the onion powder, garlic powder, paprika, 1/2 teaspoon salt and 1/4 teaspoon pepper in a separate small bowl. Set aside.
• Loosely form the beef into 4 balls; set aside. Working in batches, lightly brush the griddle with butter and toast the buns cut-side down until lightly browned, 1 to 2 minutes. Transfer to a plate.
• Brush the griddle with more butter and add 1 ball of beef. Press firmly with 2 large crisscrossed metal spatulas for exactly 10 seconds, then gently remove the spatulas. Sprinkle the patties with some of the seasoning mixture and continue cooking, undisturbed, until well browned, 1 1/2to 2 minutes. (Start cooking another burger at this point.) Flip the patty, sprinkle with more of the seasoning mixture and top with 1 cheese slice. Continue cooking until the cheese is melted around the edges and the bottom of the burger is browned, about 1 more minute. Repeat with the remaining beef.
• Spread the mayonnaise mixture on the bun tops and add some ketchup. Serve the patties on the buns with the pickles, tomato, red onion and lettuce.

Steps:

• Heat up the oil in a frying pan and add the diced onions.
• Reduce down the heat and let the onions sweat slowly, adding in the garlic to ensure it doesn't burn and become bitter.
• Add the beef to a mixing bowl and break up with your fingers.
• Tip in the onions and garlic, once cooled slightly and mix together thoroughly.
• Add salt and pepper and the dijon mustard.
• Pour in the egg and ensure that it has been mixed right the way through the beef and onions.
• Seperate the mixture into 4 portions and start moulding using your hands into burgers. Create a depression in the centre, this will ensure the burgers cook evenly and flat. Place in the fridge to chilled and stiffen.
• Once chilled and with the barbeque lit and the coals simmered down, place the burgers on the BBQ.
• Ensure that each side has sealed, if not they'll fall apart when you lift them off. Turn them over until cooked through or to the desired pinkness in the centre.
• Serve on crusty ciabatta with fresh watercress or leafy salad and enjoy. These can be frozen and defrosted for use later on.
