Recipe

Onigirazu, the no-shape sushi sandwich

Onigirazu means 'rice ball without the squeezing'. Instead of shaping rice by hand, you fold a sheet of nori around rice and fillings like a parcel, then slice it in half to show off the layers.

Why onigirazu is perfect for lunch

It holds a lot more filling than onigiri, it's easy to eat with one hand, and the cut side looks great in a box. If you can fold a burrito, you can make onigirazu.

Filling ideas

The keys to a clean cut

Stack the fillings in a tight, flat square in the center, not spread to the edges. After folding, wrap the parcel tightly in plastic wrap and let it rest for 5 minutes, seam-side down, so the nori softens and seals. Then cut through the plastic with a sharp knife wiped with a damp cloth between cuts.

Packing tip: Leave the plastic wrap on and cut through it. It keeps the halves together, keeps the nori from drying out, and makes it easy to eat at your desk.

How long it keeps

Make it the morning of, if you can. Rice hardens in the fridge, so overnight onigirazu is best left at cool room temperature for 20 minutes before eating. Keep it cold with an ice pack if your fillings include mayo, egg or fish.

Makes 2 onigirazu (2 bentos)Prep 15 min (with cooked rice)Cook none

Ingredients

  • 2 cups (about 300 g) cooked Japanese short-grain rice, lightly salted
  • 2 full sheets nori
  • 2 slices ham or spam, pan-seared
  • 1 thin omelet, folded to fit (or 2 slices tamagoyaki)
  • 2 lettuce leaves
  • 2 slices cheese (optional)
  • Plastic wrap

Steps

  1. Lay a large sheet of plastic wrap on the counter and place a nori sheet on it, shiny side down, turned like a diamond.
  2. Spread ¼ of the rice into a 4-inch (10 cm) square in the center of the nori.
  3. Stack the fillings neatly on the rice, keeping them within the square. Top with another ¼ of the rice and flatten gently.
  4. Fold the four corners of the nori over the filling one at a time, like an envelope, pressing so they stick. Wrap tightly in the plastic wrap.
  5. Rest seam-side down for 5 minutes, then cut in half through the plastic with a sharp, damp knife. Repeat for the second one.
