Fish sauce is a pungent, amber-colored liquid derived from fermented fish and salt, primarily used as a seasoning and condiment in various Asian cuisines. The highly fragrant sauce is commonly associated with Thai, Vietnamese, Filipino, and Indonesian dishes and imparts a savory, umami-rich flavor profile. Fish sauce variations exist across culinary cultures, but anchovies are commonly used as the key ingredient, contributing to its robust, salty taste.
Home cooks and consumers typically use fish sauce in small quantities, as its strong aroma is potent and can be overpowering. It is a versatile ingredient that enhances the flavors of soups, salad dressings, marinades, stir-fries, and dipping sauces. For those with dietary restrictions, a plant-based alternative made from soy sauce or liquid aminos, and seaweed can be developed to simulate similar umami characteristics.
Fish sauce is a traditional Asian seasoning known for its strong, distinctive aroma and savory, umami-filled flavor. Cooking with fish sauce can be a delicate balancing act due to its robust taste, and a little goes a long way! One common mistake when using fish sauce is overdoing it, which can be overpowering and off-putting. To get the best out of it, start with small quantities and adjust to taste. Layer the flavors gradually by adding a bit of fish sauce at the beginning of cooking and adjusting later as needed. Don't be afraid to experiment and pair it with other ingredients to balance its strong flavor. For vegan alternatives, a combination of soy sauce or tamari with kelp or other seaweed can replicate the umami taste. An underused but excellent way to use fish sauce is in salad dressings, where it adds depth and complexity. Despite its fishy aroma, when cooked, it does not impart a fishy flavor, but instead enhances the flavors of the other ingredients.

Expiration & Storage Tips
When does fish sauce expire?
Unopened fish sauce can last for 2-3 years past its printed expiration date if stored properly. This is possible because the sauce is fermented, which preserves the product for an extended period. Once you've opened the bottle, the fish sauce should remain flavorful for 12-24 months if you store it in the fridge. Freezing isn't generally recommended for fish sauce because it doesn't significantly extend the shelf life nor does it affect the flavor positively.
How do you tell if fish sauce is bad?
The primary way to tell if fish sauce has gone bad is its aroma. While fish sauce naturally has a strong, pungent smell, an off or sour odor could indicate that it's spoiled. Also, look for changes in color and consistency. If the color is darker than usual or the texture is too thick, it might be best to discard it. Lastly, if you see any mold growth or other foreign substances floating in the bottle, do not use it.
Tips for storing fish sauce to extend shelf life
• Always tightly seal the fish sauce bottle after each use. This will prevent contamination and preserve flavour.
• Store the opened fish sauce in the refrigerator. The cool temperature will slow the fermentation process and inhibit bacterial growth.
• If you use fish sauce infrequently, consider purchasing smaller bottles rather than larger ones. Once opened, it's better to use the fish sauce within a year for optimal flavour.
• Keep the fish sauce in a dark location, such as a kitchen cabinet, away from direct sunlight when not storing it in the fridge. Excessive light exposure can degrade the quality of the sauce.
• Avoid cross-contamination by using clean, dry utensils when taking fish sauce out of the bottle. Never return unused fish sauce that has been in contact with other food back into the bottle.
