Incidentally, it may be worth mentioning that T??ng ?t T?i (which won't come out correctly, so I repeat it here without diacritics : Tuong Ot Toi) is not actually a brand; it simply means "garlic chutney" in Vietnamese). The most common brand that you will find in the shops is made by Huy Fong Foods, Inc. of N. America, but it is by no means impossible that other equally good brands exist.
