Packing your first bento

The bento habit looks intimidating from the outside, all carved radishes and rice shaped like bears. Ignore that. A workday bento is ten minutes of packing what you already cooked, and the only real skills are fitting and cooling.

The box does the portioning

Pick a box and trust its size; a filled bento of ordinary dimensions is lunch, no scale required. The classic layout is half rice, a quarter something hearty, a quarter vegetables, and a divider keeps the soy sauce out of the strawberries. Pack snugly. Food that cannot slide cannot turn into abstract art by noon.

Cool it before you close it

The one rule that matters: let rice and anything cooked come down to warm-not-hot before the lid goes on. A sealed lid over steaming rice rains condensation back onto lunch, and damp lunch by noon is a sad thing. Five minutes with the lid ajar while you find your shoes is usually enough.

An onigiri press is the honest shortcut for the rice half: level in, press, turn out a tidy triangle that holds its corners in a bag. After a week the routine takes less time than the coffee, and the lunch line at work starts asking questions.
