Ingredients

  • 225g Davidstow Cornish Cheddar No. 5, grated
  • 1 tsp Worcestershire sauce
  • 1/2 tsp English mustard
  • 25g cornflour
  • 1/2 tsp dried yeast
  • 1 tsp Marmite
  • 125ml Duchy Originals From Waitrose Organic India Pale Ale
  • 50g tomato ketchup
  • 75g half-fat mayonnaise
  • 2 tsp French's Classic Yellow Mustard
  • 4 Burgers
  • 1 tbsp olive oil
  • 4 gherkins, halved lengthways
  • 4 Seeded Burger Buns, halved and toasted
  • 2 vine tomatoes, sliced
  • 1 small onion, thinly sliced
  • 2 Little Gem lettuce hearts, broken into leaves

Method

  • To make the cheese slices, line a 2cm-deep, 20x30cm baking tin with baking parchment. Mix the cheese, Worcestershire sauce, English mustard, cornflour, yeast and Marmite. Place in the fridge for 2 hours.
  • Pour the ale into a pan, set over a medium-high heat and bring to a simmer. Slowly add the cheese mixture, a handful at a time, stirring until all of the cheese has been incorporated. Allow the mixture to come to a boil and continue to whisk until smooth. Pour into the prepared tin and leave to cool to room temperature.
  • Once cool, cut into 6 squares. Cover with clingfilm and chill.
  • To make the sauce, place the ketchup, mayonnaise and yellow mustard in a bowl and mix together thoroughly. Set aside.
  • Rub each burger with a little oil and cook them on the barbecue or in a very hot pan, flipping every 15-20 seconds until cooked through. Immediately after the last flip, place a cheese slice on top of each burger and allow to melt for the final 15 seconds.
  • Place the gherkins, cut-side down, on the barbecue for about 90 seconds or until well charred.
  • To serve, place a burger topped with melted cheese on the bottom half of each bun. Add slices of tomato and onions, followed by lettuce leaves, 2 gherkin halves and a little sauce. Cover with the top half of the bun. Great served with a glass of the remaining ale.
