Yes, fish sauce is typically soy-free.
Understanding Fish Sauce and Soy Sauce
Fish sauce is a condiment produced by fermenting fish or krill in salt. Its distinct umami flavor comes from the fermentation process. Conversely, soy sauce derives its flavor from fermented soybeans, wheat, brine, and sometimes roasted grain. While both sauces contribute umami to dishes, their ingredients and resulting tastes differ significantly.
- Fish Sauce Ingredients: Primarily fermented fish (often anchovies) and salt.
- Soy Sauce Ingredients: Fermented soybeans, wheat, brine, sometimes roasted grain.
The fundamental difference in ingredients confirms that fish sauce does not contain soy. Therefore, individuals with soy allergies can generally use fish sauce without concern.
Important Note: Although most fish sauces are soy-free, always check the product label to confirm the absence of soy or soy-derived ingredients. Some manufacturers might add soy-based additives or use shared processing equipment.
