Karaage Onigiri (唐揚げおにぎり, fried chicken rice ball)

A rice ball is food with its coat already on. It asks to travel. Tuck karaage inside and it becomes a small meal in the hand: rice, salt, nori, and one soy-and-ginger piece of chicken still juicy at the center.

The fear here is not the frying. The fear is making a rice ball that falls apart, or worse, one pressed so hard it eats like paste. Warm rice is the first secret. Shape it while the grains are still tender and clinging, with wet salted hands, and the rice holds without violence. Cold rice refuses to listen. It has made its decision.

For the chicken, use thigh. Breast can be good on the plate, but in a lunchbox it grows stern. Thigh stays supple after frying, especially when the pieces are marinated briefly, dusted in katakuriko, potato starch, and fried twice. The first fry cooks it through. The short second fry dries the surface so it doesn't turn the rice greasy.

This sits naturally in bento, picnic food, and the after-school appetite that respects no schedule. Keep the seasoning plain and exact: shoyu, sake, ginger, a little garlic if you like. No heavy sauce. Nothing hidden. The rice is salted outside, the karaage seasons the middle, and the whole thing works because each part knows its job.
