Step 1

Place the passata, treacle, maple syrup, tomato sauce, vinegar, Worcestershire sauce, mustard, garlic powder and paprika in a medium saucepan. Bring to the boil over medium-high heat. Reduce heat to medium-low and simmer, stirring occasionally, for 12 minutes or until the sauce thickens. Taste and season with salt and pepper. Set aside for 20 minutes to cool slightly.

Step 2

Pour the sauce into sterilised airtight bottles. Place in the fridge until required.
