this is a very good starting recipe for burgers. change ingredients toyour taste. :-)

mix mince/ground beef with onions and pepper

mix egg yolk with the meat mixture

use the oyster sauce when mixing the ingredients. very nice alternative to salt. (not required but very nice)

store in fridge for 45 mins

make the cold mixture into little disks

place on a grill or frying pan. medium/high heat

cook until it is brown in the middle

place mayo on the rolls with the gerkins and any other things you like in the burger
