Hoisin Sauce vs Oyster Sauce – What’s the Difference?

If you are pro-Chinese food, you’re probably aware of the differences between the two sauces. If you aren’t sure, read on because we’ll explain how to tell the difference between hoisin sauce and oyster sauce in terms of taste, texture, and ingredients.

What Exactly is the Distinction Between Oyster Sauce and Hoisin Sauce?

Even though both sauces are often used in Asian foods, there are several differences between the two.

The oyster filtrate is used to make the oyster sauce. Initially, the oyster extracts are sweetened and essentially boiled down. Sugar and salt are then added. Some manufacturers might also incorporate soy sauce and corn starch into the oyster sauce to make it a little bit thicker. It’s black or dark brown.

On the other hand, hoisin sauce is entirely vegan. It is trendy in Chinese foods, particularly among vegans. It is derived from fermented soybeans. Soybeans are ground into a paste with wheat flour, then other ingredients are added, including oil, garlic, salt, and a sweetener. The sauce is reddish-brown and has a thick consistency.

Is Hoisin and Oyster Sauce Good for a Long time?

Hoisin and oyster sauce’s shelf lives are not the same. If Hoisin sauce is kept unopened, it can preserve for up to three years. Once you open it, it can last for about one to two years, only if well maintained.

Oyster sauce that is unopened should last for about 1-2 years. When it is opened, it can last up to a year when it is properly stored.

If the above sauces are used past these times, their flavor and texture change, therefore, becoming unsafe for consumption.

Is it Possible to Use Oyster Sauce and Hoisin Sauce Interchangeably?

Yes, it is possible to use the two sauces in place of each other. However, you have to be careful of the difference in flavors since the oyster sauce is saltier than hoisin. If you are using the oyster sauce in place of hoisin, use a little bit of it to avoid making your food too salty.

Since hoisin and oyster sauces are both used to make stir-fry, they can also be used interchangeably in this scenario. They can also be used interchangeably as condiments and a dipping sauce. You should also note that as much as they can be used interchangeably, it is not advisable since the oyster sauce is saltier; therefore, you will have to dilute it with a less salty sauce.
