1. First, make the caramelised onions. Melt the butter in a pan over a medium heat and add the onions. Cook for 10 minutes until softened. 

  2. Add the sugar, vinegar, Worcestershire sauce and some salt and black pepper. Cook for three minutes, stirring. 

  3. Pour in the Guinness and turn the heat to low. Add the bay leaf. Cook very gently for 30-40 minutes until the Guinness has evaporated and the onions are very soft and sticky, stirring often. Set aside. 

  4. For the burgers, grate the onion and squeeze out any liquid. Place in a large bowl and add the turkey, Worcestershire sauce, ketchup, mustard and some salt and pepper. Mix together until just combined. 

  5. Divide the mixture into four equal portions and form into 1cm-thick patties. Use your thumb to press an indentation into the centre of each one. 

  6. Heat the rapeseed oil in a large non-stick pan over a medium-high heat. Cook the turkey burgers for 5-6 minutes per side until completely cooked throughout. 

  7. Meanwhile, turn the grill on to a high heat. Lightly toast the cut sides of the burger buns. Remove to a board and layer the top buns with Brie, then place back under the grill until melted. Spread the bottom buns with a little mayo and top generously with the Guinness caramelised onions and some mixed leaves. 

  8. Place the turkey burgers over the onions and carefully add the cheesy top buns. Enjoy immediately with plenty of napkins.
