I've been looking at the Jamie Oliver recipe for Ketchup in "Jamie At Home" the only thing which looks synful is olive oil and some sugar... If I swapped them for fry light and sweetener, it'd be free, I think. The only other things it has in it is veg and ginger and red wine vinegar.... However he reckons it'll keep for up to 6 months...
By altering the recipe, do you think it'd alter the longevity of it? I presume it's the vinegar that helps it keep? Also can anyone see any errors in my "Syn free" logic?
Thanks!
