Equipment

  • Large Saucepan

Ingredients

  • 330 ml 1901 Irn Bru (See Notes)
  • 350 g Ketchup (See Notes)
  • 100 g Dark Brown Sugar
  • 75 g Black Treacle
  • 75 g Honey
  • 30 g Apple Cider Vinegar
  • 20 g Dark Soy Sauce
  • 2 tbsp Worcestershire Sauce
  • 1 tbsp Tomato Paste
  • 1 tbsp French's Mustard
  • tsp Smoked Paprika
  • 1 tsp Ground Cumin
  • ½ tsp Cayenne Pepper

Instructions

  • Pour the Irn Bru into a large saucepan then set it over a medium-high heat. Bring to the boil then reduce by half. This will take around 5 minutes.
  • Take the pan off the heat, add all of the remaining ingredients into the reduced Irn Bru then whisk to combine.
  • Place the pan back on the stove, over a medium heat then cook for 5-10 minutes, stirring frequently until the sugars & spices have dissolved & the sauce is thick.
  • Once cooked, let the sauce cool then transfer to a container & store in the fridge until needed.

Notes

1. To Cook On An Aga - Use the boiling plate to reduce the Irn Bru then cook the sauce on the simmering plate.
2. Irn Bru - Make sure to use 1901 Irn Bru (the original stuff!) as it has the highest amount of sugar & will reduce properly. Regular Irn Bru will also work but you may need to add in extra sugar, to taste.
3. Ketchup - I used Heinz tomato ketchup for my bbq sauce but other brands will work as well.
4. Storage - Kept in an airtight container, bbq sauce will keep for up to 2 weeks.
