While a bamboo mat, also known as a sushi rolling mat or makisu, is traditionally used to help roll sushi neatly and tightly, it is not absolutely necessary to make sushi. You can still make sushi without a bamboo mat by using plastic wrap or a kitchen towel as a substitute. However, using a bamboo mat can make the rolling process easier and help achieve a more uniform shape for your sushi rolls. **

You can find bamboo mats for making sushi at most Asian grocery stores, kitchen supply stores, or online retailers such as Amazon or specialty kitchenware websites. These mats are commonly used in sushi making to help roll and shape the sushi rice and fillings. They are usually inexpensive and can be reused multiple times with proper care. **

Onigiri sushi can typically last for about 1-2 days when stored in the refrigerator. However, the shelf life can vary depending on the filling and any additional ingredients used. It is important to consume onigiri sushi within a short period of time to ensure freshness and food safety. After a couple of days, the rice may become dry and the texture may change, so it is best to enjoy onigiri sushi soon after it is made. **

Bambuseae includes the majority of bamboo species and is characterized by having woody stems and a unique flowering pattern.

These lower classifications help to categorize and understand the diverse range of bamboo species found around the world. **

However, prolonged exposure to moisture and extreme weather conditions can cause bamboo to deteriorate over time.
