Tips for Preparing Onigiri

Onigiri (Japanese Rice Balls) Recipe

Making Onigiri is just a simple process, but there are a few more ways to make it easier:

  • Wet your hands. Onigiri is easier to make with damp hands. Get a small bowl of water and place it near your work surface while you shape the rice balls. Use the water to dampen your hands equally so that the rice will not stick to them.

  • Put salt in your hands. After damping your hands, shower a few pinches of salt in both of your palms. While you are shaping the Onigiri, the salt will coat the rice and help it maintain its freshness longer.

  • Use a mold. Silicone molds, which are available online or in some grocery stores, allow you to make a variety of shapes with an easy, quick process.

  • Use plastic wrap. If you are having a hard time figuring out how much pressure to help the rice keep its shape, a sheet of plastic wrap can make it a lot easier. Just put the rice on the plastic and pull it tightly and make your way to its direction to mold.

  • A rice cooker will save the day. You don’t need the rice cooker to make Onigiri, but having firm, fluffy rice to mold will make the process a lot easier.
