Ingredients Needed for Onigiri
Rice Selection – The Key Ingredient
The most important component of onigiri is the rice. Japanese short-grain rice, often labeled as sushi rice, is ideal due to its sticky texture. This stickiness helps the rice hold its shape without falling apart.

Essential Tools for Making Onigiri
To make onigiri successfully, it’s helpful to have the right tools:
- Rice Cooker: Ensures perfectly cooked rice every time.
- Onigiri Mold: Useful for shaping uniform rice balls, especially for beginners.
- Plastic Wrap: Helps in shaping without sticking to your hands.
- Nori Sheets: Adds flavor and holds the rice ball together.
- Small Bowl of Salted Water: Keeps the rice from sticking to your hands.
Preparing the Rice
Washing and Cooking the Rice
- Rinse the Rice: Wash the rice under cold water until the water runs clear. This removes excess starch for a fluffier texture.
- Soak the Rice: Allow the rice to soak in water for 20–30 minutes before cooking to ensure even cooking.
- Cook the Rice: Use a rice cooker or stovetop method. Add 1:1.1 ratio of water to rice for best results.
Seasoning the Rice for Flavor
Once the rice is cooked, let it cool slightly before seasoning. A sprinkle of salt enhances flavor, while adding rice vinegar (optional) provides a subtle tanginess. Avoid over-mixing to maintain the texture.
