Burgers are so much tastier when they are grilled instead of fried. The bread should be grilled and served warm too. Not just the burger, the bread as well. The vegetables should be cut and served fresh, not cutting them and putting them back in the fridge till you are going to make your hamburger. The burger should be beef and not pork. Beef burgers are much much tastier in a hamburger than pork burgers. Mayonaise and ketchup should be freshly made and not from a bottle. There are too much preservatives and colorants in bottled ketchup and mayo. To have the perfect hamburger the sauce needs to be freshly made as well.
