Fish sauce is a staple ingredient in many Southeast Asian dishes, adding a savory and umami flavor to everything from stir-fries to marinades.
But what happens if you forget to refrigerate your fish sauce? Is it still safe to eat? Will it go bad?
In this article, we’ll explore the ins and outs of storing fish sauce, including whether or not it needs to be refrigerated, how long it lasts, and what to do if you accidentally leave it out on the counter.
So grab a bottle of your favorite fish sauce and let’s dive in!
What If I Forgot To Refrigerate My Fish Sauce?
If you forgot to refrigerate your fish sauce, don’t panic. While it’s recommended to store it in the fridge for optimal quality, fish sauce can actually sit unrefrigerated for a period of time without going bad.
Fish sauce is made through a long fermentation and production process, which means it’s already undergone a preservation process. This allows it to sit at room temperature for a while without spoiling. However, if you want to extend its shelf life, it’s best to store it in the fridge.
If you accidentally left your fish sauce out on the counter for a few hours or even overnight, it’s still safe to eat. It may have changed slightly in flavor due to continued fermentation, but it’s not spoiled.
However, if you notice any signs of spoilage such as a strange smell or appearance, it’s best to throw it out. Spoiled fish sauce can make you sick and should not be consumed.
Does Fish Sauce Need To Be Refrigerated?
Fish sauce does not necessarily need to be refrigerated, but it’s recommended for optimal quality and to extend its shelf life. If you plan on using the fish sauce within a few weeks to half a year, it’s safe to leave it at room temperature as long as it’s sealed tightly and not exposed to direct sunlight.
However, if you don’t use fish sauce regularly or want to prolong its shelf life for more than a couple of months, it’s best to store it in the fridge. Different brands may have varying recommendations, but storing it in the fridge will ensure that it retains its quality for a longer period of time.
It’s important to note that cold temperatures can cause the salt in fish sauce to crystallize over time, so if you do choose to refrigerate your fish sauce, make sure it’s stored away from any hot areas in your kitchen and in a cool, dark place like the pantry.
How Long Does Fish Sauce Last?
The shelf life of fish sauce depends on various factors such as storage conditions, whether the bottle is opened or unopened, and the manufacturer’s expiration date. An unopened bottle of fish sauce can last up to two to three years at room temperature in a cool, dark place. However, an opened bottle of fish sauce has a shorter shelf life and should be stored in an airtight container in the fridge. If stored properly, an opened bottle of fish sauce can last up to three to six months at room temperature or up to one year in the refrigerator.
It’s important to note that the expiration date on the bottle is just an estimate by the manufacturer on how long the fish sauce will remain in its prime flavorful stage. Fish sauce contains high amounts of salt and preservatives that can lose their taste over time. Additionally, it consists of bacteria due to the fermented fish used to produce it, which can retain its taste for a couple of years before going bland.
While fish sauce rarely goes bad in terms of food safety, its quality degrades over time. After storing it for a long time, you might notice that the flavor is milder and the taste is lacking. However, many people have had fish sauce stored in their refrigerators for even five years and found that it still has the same taste and is completely good to be used.
Signs Your Fish Sauce Has Gone Bad
While fish sauce can last for a while without refrigeration, it’s important to know the signs of spoilage to avoid consuming bad sauce. Here are some signs to look out for:
1. Strange odor: If your fish sauce smells off or has a foul odor, it’s a sign that it has gone bad. The smell can range from sour to rancid and is an indicator that the sauce is no longer safe to consume.
2. Discoloration: If your fish sauce has changed color or has become cloudy, it’s a sign that it has gone bad. The color can range from light brown to dark brown, and the cloudiness is due to bacterial growth.
3. Mold or yeast growth: If you notice any mold or yeast growing on the surface of your fish sauce, it’s a clear sign that it has gone bad. These growths can be green, white, or black and are an indicator of spoilage.
4. Strange taste: If your fish sauce tastes off or has a strange flavor, it’s a sign that it has gone bad. The taste can be bitter, sour, or rancid and is an indicator that the sauce is no longer safe to consume.
If you notice any of these signs, it’s best to discard your fish sauce and purchase a new bottle. It’s important to always check for signs of spoilage before using any condiments to ensure your safety and the quality of your food.
How To Properly Store Fish Sauce
To properly store fish sauce, it’s important to keep it in a cool, dark place away from any heat sources. This could be a pantry or a cupboard in your kitchen. Avoid storing it in the fridge because cold temperatures can cause the salt to crystallize over time.
If you want to extend the shelf life of your fish sauce, storing it in the fridge is the better choice. However, it’s important to note that fish sauce doesn’t need to be refrigerated after opening, unless you plan on keeping it for more than a couple of months. If you finish the bottle within a few weeks to maybe half a year, you can leave it at room temperature.
No matter where you store your fish sauce, make sure the bottle is tightly sealed and doesn’t sit in direct sunlight. This will help preserve its quality and prevent any bacteria growth.
