In a bowl, mix the beef, onion, ham, egg, mustard, breadcrumbs and cream. Season with salt and black pepper. With wet hands, form into 4 burgers. In a separate bowl, mix the mayonnaise and ketchup. Heat the oil in a large frying pan and fry the burgers for 3-4 mins on each side, until browned. Drain on paper towels.
