For all of you people who are new to the world of sushi, we thought we would list some frequently asked questions about this Japanese dish here.

How long does sushi keep?

It is best practice to eat sushi the day that it is prepared. It can be left out for about a total of two hours at room temperature and still be safe to eat. Any longer, and it needs to be stored in a cold temperature, like the refrigerator. When eating after storing in cold temperatures, allow about half an hour for it to sit out for optimum temperature/texture. As with sushi, sashimi should also be eaten the same day it is prepared, and stored in cold temperatures after two hours.

Can I get sushi without rice?

Yes! In one of our previous blogs, we went over the difference between sushi and sashimi. While sushi dishes do use vinegared rice, sashimi doesn’t necessarily. For those of you with an aversion to rice, or who are trying to count their calories, choosing a sashimi dish probably better fits your diet.

What does “sushi grade” mean?

Many people are fooled by a claim of “sushi grade” fish. What sushi grade means is that the fish is legally safe to eat according to rules laid out by the FDA. So don’t be fooled into paying more just for a claim of sushi grade fish, as there is no criteria that must be met before making the claim other than that it is legally safe to eat. Instead, try to focus on the taste until you find a sushi dish that suits you.

Can I choose between white or brown rice?

While sushi is normally served with white rice, many restaurants offer dishes with brown rice as well. The key ingredient that makes sushi what it is is the vinegared rice, which helps to give it its distinguishing taste.

Where did sushi come from?

Japan gets credit for the concept of modern sushi, which was invented by Hanaya Yohei some time in  the end of the Edo period, around the 1800s. However, the precursor to modern day sushi, Nare-zushi (sour rice wrapped around fermented fish), originated somewhere near the Mekong River, where it then spread to China, and then later to Japan where it was modernized into the sushi that we eat today.

Why is wasabi hot?

True wasabi comes from a root of the plant wasabia japonica in Japan (many forms of wasabi use horseradish as a substitute, but that is not “true” wasabi). This root contains natural antimicrobial chemicals, which serve the dual purpose of giving wasabi its powerful flavor, as well as killing any potential microbes in the seafood.

What does the suffix “-zushi” mean?

When talking about a specific type of sushi, sushi becomes the suffix, and replaces its “s” with a “z”. So, when you hear about someone talking about nigiri-zushi, for instance, they are referring to a type of sushi (in this example, “nigiri”). Other types of sushi include makizushi, chirashizushi, oshizushi, and more.

What are some other common sushi spices?

We already talked about wasabi, which is probably the most recognized spice eaten with sushi. However, there are plenty of other spices to choose from. For instance, many sushi dishes pair well with soy sauce and pickled ginger as well. There are a lot of options when it comes to sushi, and to find the perfect dish, it’s important to try them all!
