Ingredients
  

  • 600g/1⅓lbs frozen French fries
Caramelised onions
  • 2 large brown onions diced
  • 2 tbsp butter
  • ½ tsp sugar
  • ¼ tsp salt
Sauce
  • 40g/1½oz dill pickles/pickled gherkins finely diced and patted dry
  • ½ cup mayonnaise
  • ¼ cup ketchup
  • 2 tbsp dijon mustard
  • ⅓ caramelised onions
  • 2 tsp chives finely sliced, plus extra to serve
  • 1 large garlic clove grated
  • 1 tsp vegetarian Worcestershire sauce
  • ¼ tsp sugar
American cheese sauce
  • 1½ tbsp butter
  • 1½ tbsp plain flour
  • ¾ cup milk
  • 70g/2½ American cheese slices diced
  • 45g/1½ grated Cheddar

Method
 

Caramelised onions
  1. First make the caramelised onions. Melt the butter in a frying pan or sauce pan over a medium heat.
  2. Once the butter is bubbling, add in the onions, sugar and salt. Stir to combine.
  3. Reduce the heat to medium-low. Cook for 45 minutes to 1 hour, stirring often until the onions are caramelised. Turn down the heat if the onions are starting to brown too quickly. Set aside.
Fries
  1. Cook your fries according to packet instructions. Time this so they will be ready soon after the onions have finished cooking.
American cheese sauce
  1. Meanwhile, make the cheese sauce.
  2. Melt the butter in a medium saucepan over a medium heat.
  3. Whisk through the flour and cook for 30 seconds.
  4. Whisk in the milk gradually. Continue cooking and whisking until the sauce has thickened.
  5. Turn the heat to low and whisk in your cheese until melted.
  6. Take off the heat, cover and set aside.
Sauce
  1. Whisk together all of the sauce ingredients, except the onion, in a bowl. Once the onions are cooled, stir them through.
Assembly
  1. Gently reheat your cheese sauce. Add the fries to a large bowl and load them up with the cheese sauce and burger sauce. Top with the caramelised onions and more chopped chives, if you like.
