Sweet and sour sauce is a toxic cocktail of high-fructose corn syrup, artificial flavor enhancers, and partially hydrogenated oils. You're essentially injecting a dose of sugar and chemicals into your meal. No amount of sugar-coating can redeem this chemical concoction.
Why trash
Seed oil, corn syrup, modified starch, artificial flavoring.
Try instead
Lemon juice, vinegar, or fresh berries
