How to store sushi rice overnight?

To store sushi overnight, store it in the plastic wrap and place the wrapped sushi in an airtight container or styrofoam box. Make sure that no extra water is lingering on the sushi rolls before you wrap them in plastic. The high moisture can promote the bacteria to grow on the sushi. Also, there should be no air inside the bag. Otherwise, sushi rice will get harder.

Once packed, refrigerate the airtight box on the shelf of the fridge. The refrigeration temperature is important to be 41 degrees Fahrenheit to ensure that there will not be any warmth available to make the sushi go bad.

Why should you avoid storing sushi rice overnight?

Sushi rice is a very delicate dish, and storing sushi rice needs far more care than other dishes. This is because a dish of sushi is all about taste and texture and when you store it overnight you risk messing with the taste of your dish. Your rice will have a revolting taste the next day and will not have the sticky texture required to mold sushi dishes.

Also, the starch in rice is a perishable commodity for microorganisms, particularly bacteria. These bacteria produce toxins in the rice and the worst fact is that these toxins can not be neutralized by reheating the rice. As a result, you can suffer from diarrhea and your stomach may get upset.

Therefore it is better to consume sushi rice the same day you prepare it rather than storing it overnight aiming to consume it the next day.

How to maximize sushi freshness?

As discussed earlier, sushi is a very delicate dish, and when it comes to the quality of sushi, it is all about freshness. The more fresh ingredients you use, the best quality you prepare. You might wonder here that freshness is not a subjective term, but hold on, certain practices that might help you assure the freshness and quality of your end product; sushi rice.

The first practice that you need to adopt to maximize the freshness of sushi is to buy fresh ingredients. This means you have to buy the fish for sushi rice that just arrived from the boats, vegetables, and fruits that have just come from the farm, or that you just harvested from the beautiful lawn of your home. Also, you have to use the properly packaged rice and the caviar that was correctly stored.

Next, make sure that you have the right tools to make sushi and these tools should be clean. Substitution of tools that Japanese chefs use to prepare sushi with rolling mats, cutting boards, and dishware is not recommended as the tools for sushi are specialized specifically for preparing that particular dish and for good reason.

In the end, make sure to work in an environment where the temperature is cool and the environment is clean. Also, your workstation should be away from the direct source of heat and light and do not forget to observe the food safety standards.
