Black Rice Onigiri

Prep 15 mins

Total 45 mins
Serves 4

Ingredients

  • 1.5 cups Agriko black rice
  • 2.5 cups water
  • 1 teaspoon sea salt
  • 1 tablespoon rice vinegar
  • 2 teaspoons sugar
  • 4 sheets nori seaweed, cut into strips
  • ½ cup umeboshi (pickled plums), pitted
  • 2 tablespoons sesame seeds

Instructions

  1. Rinse Agriko black rice under cold running water, stirring gently with your fingers until the water runs almost clear, about 2-3 minutes. This removes excess starch and ensures fluffy rice.

  2. Add the rinsed black rice and 2.5 cups of water to a pot. Bring to a boil over high heat, then reduce to low heat, cover, and simmer for 25-30 minutes until all water is absorbed and rice is tender.

  3. While rice cooks, prepare the seasoning: combine rice vinegar, sugar, and ½ teaspoon of sea salt in a small bowl, stirring until sugar dissolves.

  4. Once rice is cooked, transfer to a large bowl and gently fold in the vinegar mixture until evenly distributed. Let cool for 5 minutes until comfortable to handle.

  5. Dampen your hands with water and sprinkle with a pinch of salt. Grab about ¼ cup of rice and gently shape into a triangle or ball, creating a small indent in the center with your thumb.

  6. Place one umeboshi plum in the indent of each onigiri, then gently close the rice around it. Press lightly so the rice holds its shape without compacting too much.

  7. Roll sesame seeds onto the sides of each onigiri, then wrap a nori strip around the base. Arrange on a serving platter and serve at room temperature or slightly warm.

Chef's Tip

For easier handling, wet your hands between shaping each onigiri to prevent sticking, and avoid over-pressing the rice as it will become dense and chewy rather than light and fluffy.
