Rice Sandwich 2 Ways (Onigirazu)

Onigirazu
A Note on This Recipe

Have you tried onigirazu, also known as a rice sandwich? This satisfying dish is made by layering various fillings between seasoned rice and wrapping it all up in seaweed.

Think of it as a more generous, customizable alternative to onigiri. To bring all the flavors together, each variation gets its own quick sauce made from simple pantry condiments.

How to Make It

Prepare the Ingredients

Roughly shred the crab sticks into strips along their length, then cut crosswise in half. Cut the cucumber into wide, thin strips and the tomato into thin rounds. Slice the avocado thinly.

Make the Wasabi Mayo Sauce

(for the California Roll Onigirazu)
Combine all the wasabi mayo sauce ingredients in a bowl and mix until smooth.

Make the Honey Mustard Sauce

(for the Bacon, Cucumber & Tomato Onigirazu)
Combine all the honey mustard sauce ingredients in a bowl and mix until smooth.

Prepare the Rice

Place a sheet of seaweed in a diamond orientation on a flat surface. Spoon half of the rice into the center and spread it into an even square shape.

Assemble the California Roll Onigirazu

Spread the wasabi mayo over the rice. Layer the crab sticks, cucumber, and avocado on top, then spread a little more sauce over the fillings. Cover with the remaining half of the rice.

Assemble the Bacon, Cucumber & Tomato Onigirazu

Spread the honey mustard over the rice. Layer the bacon, tomato, and cucumber on top, then spread a little more sauce over the fillings. Cover with the remaining half of the rice.

Wrap

Fold the bottom corner up, then bring the two side corners in toward the center, tucking them snugly. Fold the top corner down and seal the seam with a few grains of rice.

Serve

Flip seam-side down and cut in half. If the onigirazu is having trouble holding its shape, wrap it tightly in plastic wrap before cutting.

Notes

Use room-temperature rice — hot rice will make the seaweed soggy quickly. Place moisture-heavy ingredients like tomato and cucumber in the middle of the filling stack to keep the rice and seaweed drier for longer. If the onigirazu has trouble holding its shape, wrap it tightly in plastic wrap before cutting.
