Worcestershire sauce commonly contains onion and garlic extracts as base ingredients, alongside high salt content — best avoided rather than shared.
This sauce is frequently used in marinades for boerewors, biltong seasoning, and braai marinades, and its onion/garlic base means dishes marinated in it carry the same considerations as those ingredients directly, even though you're not seeing whole onion pieces.
