Ingredients:
- 1 cup (200g) short-grain sushi rice
- 1 ¼ cups (300ml) water
- 2 tablespoons rice vinegar
- 1 tablespoon sugar
- ½ teaspoon salt
- 8 ounces (225g) cooked unagi fillet (eel), preferably vacuum-packed, skin-on.
- ¼ cup (60ml) soy sauce
- 2 tablespoons mirin (sweet rice wine)
- 1 tablespoon sake (rice wine, optional)
- 1 tablespoon sugar
- Toasted sesame seeds (optional)
- Sansho pepper (Japanese pepper) (optional)
Instructions:
- Rinse the rice thoroughly until the water runs clear. Cook according to rice cooker instructions or in a pot (bring to a boil, then simmer covered for 15 minutes, then let steam for 10 minutes).
- In a small bowl, combine rice vinegar, sugar, and salt. Stir until sugar dissolves.
- Gently fold the sushi vinegar mixture into the cooked rice. Use a cutting motion to avoid mashing the rice. Fan the rice while mixing to cool it quickly.
- In a small saucepan, combine soy sauce, mirin, sake (if using), and sugar. Simmer over medium heat until slightly thickened, about 5-7 minutes. Be careful not to burn it.
- Gently warm the unagi fillet in the oven (350°F/175°C) or microwave until heated through. Avoid overcooking, or it will dry out!
- Wet your hands with water (to prevent rice from sticking). Take a small handful of rice and gently form it into an oblong shape.
- Place a piece of warmed unagi on top of each rice ball. Brush with unagi sauce.
- Sprinkle with toasted sesame seeds and/or sansho pepper, if desired. Serve immediately with soy sauce and pickled ginger (gari).
