A perfect burger to me is a paddy (rissole size) lettuce on the bottom, then the paddy, then tomato, pineapple, beetroot and onion then cheese on top.
In a bread bun not a fucking brioche thing.
If I’m extra fancy an egg under the cheese but the egg needs to be so close to solid that it runs and cooks solid at the same time. I hate the smell of runny egg.
What ruins a burger for me, fucking sauce I don’t want your drippy shitty BBQ sauce or whatever sogging up my bread.
Make a good paddy and that will carry the burger
