Wakame Onigiri (Seaweed Rice Balls)

わかめおにぎり · Wakame Onigiri

By Aoi, licensed nutritionist · From a Japanese preschool lunch menu

Onigiri are Japanese rice balls, and this version folds in tender wakame seaweed, finely shredded carrot and shirasu (tiny dried baby sardines) for a gentle, savory flavor. The filling is simmered in dashi with a little sugar and soy sauce until the liquid is absorbed, so every grain of rice picks up the taste without any pieces falling out. Small hands can hold these easily, and the soft, mild seasoning makes them a favorite even with children who are wary of seaweed or fish.

Directions

  1. 1

    Soak the rice in water for at least 30 minutes. Add one-third of the seasonings and cook the rice.

  2. 2

    Cut the carrot into short, fine matchsticks. Rehydrate the wakame in water and chop it finely. Briefly blanch the shirasu in boiling water to remove excess salt.

  3. 3

    Heat the oil in a pot and stir-fry the carrot. Once it is cooked through, add the dashi stock, the remaining seasonings, the wakame and the shirasu, and simmer over low heat until the liquid has cooked away.

  4. 4

    Mix the cooked rice from step 1 with the mixture from step 3, then shape into onigiri.

The salt in the seasonings gets in the way of the rice absorbing water, so always soak the rice first and stir in the seasonings just before you start cooking it.
