Add the tomato puree/passata to a pot on medium to high heat, stir for 1 minute until heated
Add the apple sauce and stir through. Next add the tomato paste, honey, soy sauce, worcestershire sauce and vinegar and stir for a further 3 minutes until hot (don’t bring it to the boil as this will thin it our too much)
Add the garlic salt, onion salt, ground paprika and smoked paprika and stir through.
Remove from heat and let stand for 10 minutes.
Pour sauce into a jug with a spout and pour into sauce bottle (I used glass, but plastic sauce bottles would work too.) Secure lid tightly and refrigerate overnight before using.
