Does Oyster Sauce Need To Be Refrigerated

Are you looking to add Oyster sauce to your pantry but bothered about the best storage method? Are you curious to know the answer to the question: does Oyster sauce need to be refrigerated?

Oyster sauce should be stored in a cool, dark place, such as the pantry, at a constant temperature, away from hot appliances like the stove or dishwasher. Once opened, the oyster sauce should be refrigerated in its original glass container, with the top properly closed. 

If your sauce came in a can, store it in a plastic or glass container in the refrigerator. Some of the benefits of effective food storage include eating healthier, saving money on food, and helping the environment by reducing waste. In this article, you will understand more about the oyster sauce.

Does Oyster Sauce Need To Be Refrigerated

Oyster sauce is a sauce with a syrup-like texture widely used in Chinese cuisine. Like every sauce, you need to store it to ensure it doesn’t go bad. Would you like to know if you need to start refrigerating oyster sauce for storage purposes?

It’s not necessary to keep soy sauce refrigerated, though it’s a good idea. If refrigerated, soy sauce will keep its best quality for at least a few months, but only about a month if left at room temperature once opened.

To put it another way, if you don’t use soy sauce frequently, it’s best to keep it in the fridge. Furthermore, well-known brands like Kikkoman and Kamada recommend keeping soy sauces refrigerated after opening to maintain the highest quality.

However, nothing bad should happen if you leave your soy sauce out of the refrigerator. As I mentioned in the spoiling section, soy sauce should be safe to use even if it isn’t in the fridge. The worst-case scenario is that its quality will deteriorate faster than you’d like, forcing you to go to the store and purchase a new bottle sooner than you’d like.

Will Oyster Sauce Go Bad If Not Refrigerated?

You’ve probably heard of condiments like soy sauce and vinegar, which don’t need to be refrigerated once opened. So, will oyster sauce go bad if not refrigerated?

Oyster sauce is a different story. However, ensure you do not get too far ahead of yourself. Let’s go over it step by step and explain why. After you’ve opened a bottle of oyster sauce, store it in a cool, dark place. A shelf in an old pantry is ideal, but any cabinet that stays cold and isn’t overly bright will do.

It must be kept in an airtight container. The bottle you bought it in will be fine if you screw the top back on tightly. If you bought it in a can, refrigerate any leftovers in a plastic or glass container with a tight lid after opening.

The well-known brand Golden Dragon recommends that you refrigerate their items after opening, but this is not required. However, storing such products at low temperatures will allow them to last longer. Other brands, such as Maekrua, do not make this distinction. “Refrigerate after opening,” their products state clearly on the packaging.

It won’t go bad if you leave an opened bottle of oyster sauce out at room temperature for a few days (or even weeks) (or even weeks). However, the quality will degrade faster than if stored in a cool environment, so refrigeration is usually the best option.

How To Store Oyster Sauce

I’m sure you’re familiar with condiments like soy sauce or vinegar that don’t need to be refrigerated after opening. Oyster sauce isn’t exactly the same, but let’s not get too far ahead of ourselves. So, how can you store oyster sauce?

To begin, keep the unopened oyster sauce in a cool and dark place. A kitchen cupboard or a shelf in the pantry will suffice. Now comes the tricky part: should you refrigerate oyster sauce after opening it? The best answer I can give you is: you should probably.

According to Golden Dragon Sauces’ website, refrigeration of their products is recommended but not required. The cold temperature simply helps to preserve the quality of the condiment for a longer period of time. Other brands, such as the popular Maekrua, slap a large label on the bottle that says refrigerate after opening. That implies that you should keep the sauce in the refrigerator.

Overall, the oyster sauce will not spoil if left at room temperature for a few days or even weeks after opening. However, the quality will degrade much faster, so unless you intend to finish the bottle soon, refrigeration is the best option.

How To Tell If Oyster Sauce Is Bad?

how to tell if oyster sauce is bad

You’re probably aware that distinguishing between spoiled and safe-to-eat sauces can be difficult. So, how can one tell when their soy sauce is bad and probably unsafe to eat? 

There are some telltale signs that your oyster sauce is past its primes, such as the presence of white or green fuzz on the surface or an unpleasant odor. But things are definitely not always as easy as we would like.

Oyster sauce darkens and intensifies in flavor over time. If it’s too strong for you and using less sauce in your dishes doesn’t cut it, feel free to throw it out. The sauce isn’t bad by any means, but it’s pretty useless, so there’s no reason to keep it around.

Another thing to know is that the sauce is thickened during the manufacturing process, often with cornstarch. And if water begins to separate on the surface, it means the condiment is past its prime. Giving it a good stir (as you would with yogurt) will not solve the texture problem. Get rid of it immediately if that is the case.

Difference Between Oyster Sauce and Fish Sauce?

Every sauce has its distinguishing factor, and the same can be said for oyster sauce and fish sauce. Would you like to know what are the differences between oyster sauce and fish sauce?

While soy sauce can be substituted for oyster sauce, fish sauce has a distinct flavor that cannot be replicated. In contrast, soy sauce may work in some recipes that call for fish sauce. As the names suggest, oyster sauce is made from oysters, and fish sauce is made from fish. The method of preparation varies, as do the main ingredients. 

The two sauces differ in terms of color, consistency, and flavor. However, in some recipes, they can be substituted for one another. It’s always a good idea to have a basic understanding of these sauces if you intend to use them.

Oyster sauce is made by simmering oysters in water until the liquids have reduced to form a thick sauce. Nowadays, most store-bought versions are made with sugar, salt, and cornstarch. They have a small amount of oyster sauce or oyster essence for flavor. There is also vegan oyster sauce made from shiitake or oyster mushrooms.

Fish sauce is made by fermenting fish and seasoning it with salt. While anchovies are the most commonly used fish in this sauce, other types of fish are occasionally used. By fermenting it for a short period of time, you can create a sauce with a strong fishy flavor. If the fermentation process is prolonged, the sauce will have a rich, nutty flavor. The longer the fermentation period, the less fishy the odor. Fermentation can take anywhere from a year to 18 months.

Fish sauce has a reddish brown or amber color, whereas oyster sauce has a brownish color. Spices, garlic, and green chilies may also be found in some types of fish sauce. Oyster sauce has a thick viscosity, whereas fish sauce is watery and clear.

Because it is made by reducing oyster extracts, oyster sauce is sweet with a salty undertone. Fish sauce, on the other hand, tastes saltier and nuttier. It also smells fishy. You can get rid of the odor by combining it with a small amount of lime juice. It can definitely be used in small amounts. In terms of sauce, the oyster sauce has a milder flavor than fish sauce. Oyster sauce is delicious right out of the bottle.

Does Oyster Sauce Have Oysters In It?

Oyster sauce is a salty seasoning widely used in stir-fries. It can also be used in marinades, soups, and stews, and you can also dribble it in your vegetables. Are you curious to know if the oyster sauce has oysters as one of its ingredients?

Yes. Oyster sauce is made with oysters. It has an umami flavor and can be used interchangeably with some modifications. To make a good substitute for oyster sauce, combine Worcestershire sauce, soy sauce, and sugar in a small amount.

If you’re making a stir-fry or marinade, start with soy sauce, then add a little sugar and finish with a few drops of Worcestershire sauce. This combination should add a flavor burst to the dish without overpowering it.
