What Is Fish Sauce?
Fish sauce is an ingredient used in many Asian, especially Thai and prominent Vietnamese dishes, such as Thai curries or Vietnamese pho. However, nowadays, this dipping sauce has appeared all over the world, as more and more people want to try it.
Despite its intense smell, fish sauce brings a savory but not over-salted flavor and makes the food taste perfect and bold. For instance, when added to mango salad, one of the most popular Thai appetizers, fish sauce is the highlight that brings out the refreshing flavors of the dish.
It is a sauce that is made with the simplest ingredients: Fish and salt. However, these days, commercial fish sauce often contains sugar, food additives, and preservatives to prolong its shelf life to meet the market’s vast demands. (1)

These Identify Signs Of Spoiled Fish Sauce Will Blow Your Mind!
Although the fish sauce is not rapidly spoiled after the best-by date printed on the label, it gradually deteriorates its pure flavor. Moreover, if you do not seal it carefully, it will spoil faster. Check the following signs to know whether your fish sauce is spoiled or not.
1 Fish Sauce Gives Out A Bad Odor
Fresh fish sauce often has a featured fishy smell. However, if you notice any unpleasant or rotten smell of your fish sauce, get rid of it!
2. Your Fish Sauce Starts To Grow Mold
If you see the mold developing inside the fish sauce bottle cap or the neck of the bottle, it shows that your fish sauce is rotten. You should toss it right away.
3. Your Fish Sauce Tastes Different
Discard your sauce immediately if you detect something weird in the flavor of the fish sauce. To be specific, if it tastes bitter or sour, it means that the condiment is no longer safe for consumption.
While these above signs show spoiled fish sauce; if you notice any symptoms below, it does not mean that your fish sauce is rotten, so do not worry!
1. You Notice Clear Crystals
If you notice clear crystals in the bottom of the fish sauce bottle, it is just the salt. So, do not worry, it is not a rotten sign of fish sauce.
2. There Are Cloudy Particles In Your Fish Sauce Bottle
Those cloudy particles that you notice are just the proteins formed in the process of protein precipitation. It happens when your fish sauce stored place changes the temperature. It will not affect the fish sauce quality.
3. There Is A Discoloration Of Your Fish Sauce
The colors of fresh fish sauce are usually brownish-yellow or reddish-brown. As time goes by, your fish sauce will slowly turn to a darker color. It is a natural process, and it will not affect the fish sauce quality.
Try These Two Most Effective Ways To Store Fish Sauce!
The way you store fish sauce plays a vital role in its shelf life. As a preserved condiment, there are not many ways to keep fish sauce. The two following ways can store the unopened and opened fish sauce.
1. Place Fish Sauce In The Kitchen Cabinet Or Pantry
Although there are many differences between fish sauce and oyster sauce, their storage methods are more or less the same. If it is unopened you can place it in your kitchen cupboard or pantry.
However, make sure that your fish sauce has to be stored in a dry and cool place. Keep it away from the heat or humid areas (stove, dishwasher,etc) and avoid light. It’d be best to keep your fish sauce at a constant temperature.
Many Asian people store the opened fish sauce in their kitchen, even on the kitchen counter, so they can use it right when they want.
However, the fish sauce has to be sealed carefully after use to avoid the growth of bacteria. Also, you need to check the bottle cap where it grows mold or not to clean it immediately. If you do not do that, your fish sauce will start to spoil faster.
Another caution is that the kitchen should be clean, dry, and cool. Do not forget to clean your kitchen correctly. You also need to keep your fish sauce away from the heat from the stove or dishwasher. You should store it at a constant temperature.
2. Store Fish Sauce In The Refrigerator
If you occasionally use fish sauce or buy it because you want to try some new recipes that call for it, refrigerating is the best way to store the fish sauce for a longer period, especially after opening.
Remember to seal it carefully and put it in the refrigerator after use to keep its flavor and best quality. It will keep for 12 months in the refrigerator.
When your fish sauce is near its expiration date, you should consider other unconventional uses to ensure that it’ll not go to waste. One of my favorite ways to use up fish sauce is combining it with tamarind concentrate to whip up some stand-ins for Worcestershire sauce.
