Cooking Time : 30 Minute

Ingredients

• red onion 1 small, tough outer layers peeled and discarded
• steak mince 400g
• celery salt 1 tsp
• flat-leaf parsley a handful, finely chopped
• prosciutto 4 slices
• oil for frying
• raclette (or use another melty cheese, such as taleggio) 4 slices
• shredded lettuce to serve
• brioche-style burger buns 4, toasted

BURGER SAUCE

• mayonnaise 4 tbsp
• sweet American mustard 3 tsp
• cornichons 6, chopped
• pickled onions 4, chopped

Method

• STEP 1

  Grate the onion with a box grater.

• STEP 2

  To make the sauce, mix the mayo, mustard, cornichons and pickled onions and season.

• STEP 3

  To make the burgers, put the mince, onion, celery salt and parsley in a bowl. Season with pepper and mix well, then divide into four balls. Form each ball into a thin patty – they will shrink as they cook so make the burgers larger than your buns.

• STEP 4

  Grill the prosciutto for 2-3 minutes until crisp, then take out but leave the grill on.

• STEP 5

  Heat a large, heavy frying pan to hot. Oil and season the burgers then cook for 2 minutes each side until golden and cooked through.

• STEP 6

  Put a slice of raclette on each burger and grill for 2 minutes on high until bubbling.

• STEP 7

  Add some lettuce to each bun. Sit a burger on top, add the crispy prosciutto, spoon over the sauce and put on the bun top.
