Preparation
Slice the onion into rings. Melt the butter and use this to fry the onion rings with the sugar. Caramelise the rings, then add balsamic vinegar and fry for another 5 minutes on low heat. Season with salt and pepper. Next, mix the mayonnaise and the Spanish paprika. Take the meat from the fridge and let it come to room temperature. Mix the meat with the soy sauce and the Worcestershire sauce and add salt and pepper to taste. Roll balls of approximately 180 grams each and flatten these to form burgers. Coat the burgers with olive oil and fry in a frying pan for 4 to 5 minutes on each side until browned. Meanwhile, fry the pancetta in another pan until they are slightly crispy. Lay pancetta and a slice of Old Amsterdam on top of each burger. Cover with the lid and let the cheese melt for about 30 seconds. Cut the tomato into four thick slices. Spread a thick layer of the spicy mayonnaise on 4 slices of bread. Add a slice of tomato, a burger, and finally a good helping of the caramelised onion rings and top it with another slice of bread each.
