I first learned of Red Boat fish sauce on a cooking program. It simply stated how much superior it was to it's competitors. I could not find it in any local markets, so I tried Ebay.. Your sauce is everything that I expected and more.
This fish sauce is by far the best tasting sauce and is made on Phu Quoc Island. I had the fortune to tour the factory and also watch the fishermen off-load the anchovies from the fishing boats. Ingredients are anchovies and salt.
