I got da recipe from that basehead.

For The Patties:
1lb/500g ground beef (how to grind your own meat)
1 half onion grated or finely chopped
4 pinches ground coriander
4 pinches paprika powder
a little pepper, fresh ground is better
a little salt
1 hand fresh bread crumbs
1 egg lightly beaten
1 quarter beef stock block dissolved in a quarter cup water

For the Rolls:
4 rolls
sliced tomato
thinly sliced onion
lettuce
a few slices of gherkin
mayonnaise
ketchup

Mix all the patty ingredients thoroughly, leaving the salt for after the patties are cooked if you prefer (how to season meat).
Make sure the mixture is cool. Divide mixture into 4 equal balls and mold into patties (how to mold patties).

Cook on medium heat under the grill, on the barbecue or in a pan (how to regulate cooking temperature) untill the patty is cooked to your preferred degree of doneness or the internal temp reaches 160F/70C (when is my patty cooked?).

Split the rolls and toast the cut surfaces lightly (under grill, on barbecue or in a pan) just before the patties are done. Spread mayonnaise on the bottom halves, add a thin slice of onion, some lettuce, a slice of tomato and a little sliced gherkin. Top it off with a little mayo and ketchup, the patty and the top half of the roll.

Watts up.............
