What Is Wasabi?

Wasabi is a traditional Japanese condiment, made of Japanese horseradish, related to mustard. The wasabi horseradish grows along streams in river valleys in Japan and is then made into a spicy green paste.

Wasabi is eaten in small amounts with sashimi, sushi, and soba. The latter is a noodle dish and very easy to make, even if you’ve never cooked Japanese before!

Signs Wasabi Has Spoiled

When it comes to wasabi paste, if you’re worried it might have gone off, check for changes in appearance, smell, and taste – and in that order.

Be sure to check the surface of the paste for any discolorations or bluish or grayish specks. If you find any, get rid of it. The next thing to do is to smell it. If it smells off, discard it.

If your paste looks and smells fine, then taste a small amount. If it’s lacking flavor or not up to standard, you can throw it out for quality purposes.

Powdered wasabi, on the other hand, stays safe to consume indefinitely. Unless water gets to the package, in which case mold or a big clump will be present. If it looks as usual, then it should be okay to eat. 

Storing Wasabi

When it comes to wasabi paste, which is made from horseradish, mustard, starch, and green food coloring, the storage instructions are similar to mustard.

A container of wasabi that is unopened should be stored in a cool and dark place, away from sources of heat and sunlight. The pantry or kitchen cupboard will do. As long as the wasabi isn’t near the stove.

Once the container is opened, store it in the fridge. Make sure to re-seal it tightly always, as this will prevent bacteria or moisture from getting in your wasabi.

With powdered wasabi, make sure to keep it in a resealable or airtight container upon opening. It should be stored away from moisture in a cool, dark cupboard.

How Long Does Wasabi Last?

Wasabi paste comes with a best-by date on the label. It should stay fresh for 3 months past the best-by date if unopened. Once you open the container, wasabi paste will last 3-4 months in the fridge.

Powdered wasabi will deteriorate over time. Whether is it unopened or opened, it can retain its best quality for 6-12 months after the best-by date.

If you’d like to test its potency, rub some powder between your fingers then taste and smell it. If the flavor is barely noticeable, get rid of it. Remember to wash your hands thoroughly after doing this test.

Health Benefits Of Wasabi

Wasabi has antibacterial effects that may reduce or prevent the risk of foodborne illnesses. It contains anti-inflammatory properties, as well as compounds that suppress the growth and formation of fat cells.

It may also have promising health benefits related to bone and brain health.         

The Verdict On Wasabi

Wasabi is extremely difficult to grow since it enjoys a cool, moist environment with no direct sunlight and its stem and root partially submerged along stream beds.

Wasabi paste lasts for a few months while the wasabi powder is indefinite. The only time the powder will spoil is if it water gets to it, although it will lose quality over time. Therefore, make sure to store both types of wasabi properly to ensure they keep fresh for longer.
