  • A little effort

We like our burgers piled sky-high with ‘the works’ – that means EVERYTHING including our secret sauce (made from four very simple ingredients), sweet and sour onions, emmental cheese, gherkins, frilly lettuce, and more…

Ingredients

  • steak mince 500g
  • red onion 1/2 Worcestershire sauce celery salt 1/2 tsp
  • chilli flakes a pinch
  • brioche burger buns 4 (Waitrose and M&S sell brioche-style burger buns), toasted
  • vine tomatoes 2, sliced to serve
  • emmental 8 slices
  • gherkins sliced to serve
  • frilly lettuce to serve
  • red wine vinegar 2 tbsp
  • golden caster sugar 2 tsp
  • red onion 1/2, very finely sliced
  • mayonnaise 2 heaped tbsp
  • French’s American mustard 2 tsp
  • gherkins 1 tbsp, very finely diced plus 1 tsp vinegar from the jar ketchup 1 tbsp 

Method

  • Step 1

    Mix the burger sauce ingredients together. If you have time, leave the sauce ingredients for a few hours or even make it the day before.

  • Step 2

    To make the sweet and sour onions, mix the vinegar and sugar in a bowl and toss the sliced onions in it. Stir now and again while you make the burgers.

  • Step 3

    Put the mince in a bowl. Grate the onion on the course side of a box grater.The tougher outer layers will refuse to grate, so just discard these. You just want the grated purée. Add the grated onion to the mince bowl along with a splash of Worcestershire sauce, celery salt, and chilli flakes. Mix everything with your hands and divide into 8 equal portions.

  • Step 4

    Flatten each portion into a very thin patty.They will spring back in the pan so make them much thinner than you think you should.

  • Step 5

    Heat a non-stick frying pan on a high heat.Turn the oven to 200C/fan 180C/gas 6. Fry the patties for 2 minutes each side.You won’t be able to get all 8 in one pan, so as you finish, transfer them to a baking tray.When you have 8, top each with a square of cheese and put in the oven for 2-3 minutes until the cheese melts.

  • Step 6

    Put some sauce on each bun base. Add lettuce and a couple of slices of tomato. Stack up 2 patties with cheese, then add sauce, the onions and gherkins. Add more sauce, the bun tops and skewer each to hold it together.
