For this ultimate burger, I like to go with a steak mince with a nice fat content, like chuck. Get some thick flavourful streaky bacon and some fresh and crisp vegetables. You can't really go wrong, this is my ultimate and regardless of what my husband says, it is socially acceptable to eat two burgers in one sitting.
Serve with your favourite burger buns and toppings. When it comes to burgers, I'd say that the toppings are as important as the burger itself.
