Ingredients

• 2 cups Japanese short-grain rice
• 2.5 cups Water
• 0.5 teaspoons Salt
• 1 cup Mushrooms (shiitake or button, finely chopped)
• 2 tablespoons Soy sauce
• 1 teaspoon Sesame oil
• 2 tablespoons Pickled ginger (gari, finely chopped)
• 4 sheets Nori sheets (cut into strips)
• 0.25 cup Water (for shaping)
• 0.25 teaspoon Salt (for shaping)

Directions

Step 1

Rinse the Japanese short-grain rice under cold water until the water runs clear to remove excess starch, then drain well.

Step 2

In a medium pot, combine the rinsed rice and 2.5 cups of water. Bring to a boil over high heat, then reduce the heat to low, cover with a lid, and simmer for 15 minutes. Turn off the heat and let the rice rest, covered, for an additional 10 minutes.

Step 3

While the rice cooks, heat 1 teaspoon of sesame oil in a pan over medium heat. Add the finely chopped mushrooms and sauté until softened, about 5 minutes.

Step 4

Stir in 2 tablespoons of soy sauce with the sautéed mushrooms and cook for another 2 minutes, until the liquid is mostly absorbed. Remove from heat and allow the mushroom mixture to cool.

Step 5

Once the rice is slightly cooled but still warm, stir in 0.5 teaspoons of salt to season it evenly.

Step 6

Prepare a small bowl with 0.25 cups of water and 0.25 teaspoons of salt for hand-dipping while shaping the onigiri to prevent sticking.

Step 7

Dip your hands lightly into the salted water, scoop about 1/3 cup of rice, and flatten it slightly in your palm. Place approximately 1 teaspoon of the mushroom mixture and a small amount of the chopped pickled ginger in the center.

Step 8

Mold the rice around the filling, shaping it into a triangle or ball, ensuring the filling is fully enclosed. Repeat with the remaining rice and filling.

Step 9

Wrap a strip of nori around the bottom of each onigiri or place it on one side for easier handling.

Step 10

Serve immediately, or wrap the onigiri individually in plastic wrap to keep them fresh if storing for later.
