Ingredients

  • 1/2 small skinless chicken breast about 4 ounces (100 grams)
  • 1/4 onion
  • 1 teaspoon oil
  • 2 tablespoons (30 milliliters) white wine or sake
  • 1 tablespoon tomato paste
  • 1 teaspoon soy sauce
  • 2 cups (400 grams) warm steamed rice
  • 1/2 teaspoon salt
  • 1 tablespoon (15 milliliters) water
  • 2 teaspoons butter
  • 3 eggs
  • 2 tablespoons (30 milliliters) milk
  • 1/2 tablespoon mayonnaise
  • salt and pepper

Instructions

  • Cut the chicken breast into small pieces. Finely mince the onion.
  • Heat the oil in a medium skillet, add the onion, and sauté over medium heat.
  • When translucent, add the chicken and sauté until it changes color.
  • Add the wine, tomato paste, and soy sauce and simmer until thick, about 1 minute.
  • Place in a bowl with the rice and mix gently.
  • In a small bowl, stir 1/2 teaspoon of salt into 1 tablespoon (15 milliliters) of water.
  • Divide the rice into 4 portions (1/2 cup, 100 grams each) and form into onigiri by dampening your hands with the salt water, scooping the rice into your palm, and quickly but lightly pressing it into a cylinder. Rotate it several times while pressing to make the shape even.
  • In a small bowl, whisk together the eggs, milk, mayonnaise, and salt and pepper.
  • Melt the butter in a medium skillet or rectangular Japanese omelet pan.
  • Pour in half the egg mixture and cook on both sides to form a thin omelet.
  • Repeat with the remaining egg.
  • Cut each in half and wrap around the onigiri.
