What Exactly Is Onigiri?

Before we dive into the art of cooking the rice, lets talk about what makes onigiri so special. Onigiri, often referred to as rice balls, are essentially seasoned rice formed into various shapes, often filled with savory ingredients such as umeboshi (pickled plum), salmon, or tuna. They are either wrapped in seaweed or coated with sesame seeds for added flavor.

The foundation of a good onigiri lies in the quality of the rice. Soft, sticky, and perfectly cooked Japanese short-grain rice is a mustand the easiest way to achieve that perfection is through the convenience of a rice cooker.

Ingredients Youll Need

  • 2 cups of Japanese short-grain rice
  • 2 cups of water
  • 1 tsp salt
  • Optional seasonings: rice vinegar, sugar, sesame seeds
  • Fillings: tuna with mayo, cooked salmon, or pickled plums (umeboshi)
  • Seaweed (nori) sheets, cut into strips

How to Prepare and Wash Rice

The texture and stickiness of Japanese rice are critical to shaping onigiri. Start by thoroughly rinsing the rice:

  • Measure 2 cups of rice using the measuring cup that comes with your rice cooker for accuracy.
  • Place the rice in a bowl and fill it with cold water. Swirl gently for 20-30 seconds.
  • Drain the water and repeat 3-4 times until the water runs clear. This step removes excess starch, preventing the rice from becoming too sticky or mushy.

Cooking Rice in the Rice Cooker

Once the rice is clean, transfer it to the rice cooker. Add 2 cups of water and let the rice soak for about 30 minutes. Soaking ensures even water absorption, which is crucial for achieving that perfect texture.

Turn on your rice cooker and select the white rice option (this may vary based on your machine). Most cookers will take 20-30 minutes to finish cooking. Avoid opening the lid during the process, as this could disrupt the steam and negatively impact the texture.

Seasoning the Rice

To elevate the flavor of your onigiri rice, consider adding a light seasoning. Mix 2 tablespoons of rice vinegar, 1 teaspoon of sugar, and a pinch of salt in a small bowl. Gently fold this mixture into the warm rice using a cutting board or rice paddle to avoid breaking the grains. Be sure not to over-mix.

Shaping Your Onigiri

This is the fun part! Before forming the rice balls, moisten your hands with water and sprinkle a touch of salt onto your palms to keep rice from sticking and to add flavor. Take a handful of rice and create a small indentation in the center. Place your filling of choicesuch as a spoonful of tuna mayo or pickled pluminto the dimple, then cover it with more rice to seal the filling.

Gently press and shape the rice into a triangle, oval, or ball, depending on your preference. Finally, wrap the onigiri with a strip of nori seaweed for additional flavor and structure.

Storage and Presentation

Onigiri can be enjoyed both fresh and later in the day. Store them in an air-tight container or wrap in cling film to prevent them from drying out. Avoid refrigerating if possible, as this can harden the rice. Instead, try to consume within the same day for the best taste.

Creative Variations

  • Spicy Onigiri: Add sriracha or wasabi to your filling for an adventurous kick.
  • Cheesy Onigiri: Mix shredded cheese into warm rice for a gooey surprise.
  • Vegetarian: Use finely chopped pickled vegetables as a filling.
