Ingredients
For the burger
- 70g/2½oz fresh white breadcrumbs
- 2 tbsp whole milk
- 500g/1lb 2oz beef mince
- 1 garlic clove, crushed
- 1 tbsp tomato purée
- 1 tbsp Worcestershire sauce
- 2 tbsp chopped flatleaf parsley leaves
- 12 thin slices round pancetta
- salt and freshly ground black pepper
For the tarragon mayonnaise
- 150g/5½oz mayonnaise
- 1 tsp Dijon mustard
- 1 tbsp chopped fresh tarragon leaves
To serve
- 6 ciabatta or crusty bread rolls, halved
- 60g/2¼oz spinach leaves
- 150g/5½oz caramelised onion relish, from a jar

Method
Put the breadcrumbs and milk in a bowl, mix and set aside for 5 minutes, or until the milk is absorbed. Add the mince, garlic, tomato purée, Worcestershire sauce and parsley, season with salt and pepper and mix well.
Shape the mixture into six large, flat patties. Place a slice of pancetta on both sides of each patty. Heat a large frying pan over a high heat. Add the patties and cook, in batches, for 4 minutes on each side, or until the pancetta is cooked and the burgers are done to your liking.
For the tarragon mayonnaise, put the mayonnaise, mustard and tarragon in a bowl and mix. Set aside.
Preheat the grill to high, then toast the rolls. Spread them with the tarragon mayonnaise and top with the spinach, patties, caramelised onion rellish and Cheddar. Serve with the gherkins.
