In reply to The Lemming:
Get about 1 kg of good quality steak. Mince using a cleaver on a cutting board if you don´t have a butcher´s cutter. Do not mince using a regular meat grinder: You want small, cleanly cut chunks of meat, not mince consisting largely of meat paste.
Add any spices except the salt already at that step, I usually use pepper, rosemary leaves and chilies according to taste.
Add one egg, mix, and form about 6-8 burger patties, salt them on the outside only just before frying.
I normally use a hot pan to close the outer pores and then flip the burgers to a cooler pan, or just turn down the heat after a minute or so if cooking on gas. BBQing the burgers is of course even better. In any case, quickly fry on both sides, then only turn once more. If you don´t feel confident, use a cooking thermometer.
As for the bun, either bake your own, or get some Italian ciabatta. American style foamy buns are absolutely evil.
I also put raw onions, grilled paprika, and salad leaves on the buns, as well as a dash of good steak sauce, and some homemade chilie or Jamican jerk sauce. Even coming close to these burgers with a ketchup bottle is a capital offence!
