What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Rinse the sushi rice until the water runs clear to remove excess starch and prevent mushiness.
- 2Rest the grilled chicken for 3 minutes before slicing so juices redistribute and meat stays tender.
- 3For perfect soft-boiled eggs, set a timer for 6.5 minutes and transfer immediately to an ice bath.
- 4Brush the reserved teriyaki marinade only during the last 2 minutes to avoid burning the sugars.
- 5Peel soft-boiled eggs under a thin stream of cold water for neater, easier removal of the shell.
- 6Store the assembled bento without the egg halved, then halve it just before eating to keep the yolk runny.
- 7Toast sesame seeds in a dry pan for 1 minute until fragrant for deeper nutty flavor.
