500g mince beef (get 80% lean beef and 20% fat - burgers need the fat for flavour and to help bind them)
Half an onion (red is best but normal is fine) chopped very fine
One whole egg beaten up
3 tspn California Rancher Rump Rub Seasoning
Good slug of worcester sauce (about a tablespoonful)
Good slug of oyster sauce
Handful of breadcrumbs
Add all the ingredients to a bowl and mix well with your hands
Place in the fridge for an hour to firm up and allow the flavours to develop
Divide into four and make into burger patties. Push your thumb gently into the centre of your burger before it goes on the grill. This will compensate for the burger wanting to ball-up as it cooks and you'll end up with a nice flat burger.
Place burgers on a really hot, oiled grill and leave them for 4-5 mins. Flip them over and just leave them again for another 4-5 mins. Don't fiddle.
Serve with sliced gherkins, thinly sliced cheese, tomato relish, lettuce, Oaky & Smoky BBQ Sauce and mayo on BBQ toasted sesame seed buns.
