Red Boat 40° N Fish Sauce. The best fish sauce on the market! Made from wild-caught black anchovy and sea salt from our neighboring island of Phú Quốc, Vietnam. Single-press Red Boat 40°N is barrel-aged using a centuries-old fermentation tradition. No preservatives or MSG. Just unsurpassed quality and flavor. The traditionally crafted fish sauce is matured in wooden barrels for one year. Grade N is an industry standard that indicates the protein content and quality of fish sauce. Commercially available fish sauces are usually less than 20° N. Red Boat is 40° N. Use this fish sauce “neat” over roasted salmon, halibut or scallops, toss with sautéed greens and lemon or blend with butter and smear over a freshly seared steak or lamb chops. It’s particularly good with lime, Red Kampot Pepper and palm sugar as a dipping sauce or salad dressing. Think of it as liquid umami that can be used in marinades, dressings, soups or stews.
