プログレッシブ和英中辞典(第4版)

せきはん【赤飯】

steamed rice (mixed) with red beans (and served especially on celebratory, congratulatory occasions)

説明
Sekihan (literally “red rice") is a red-bean rice dish served on celebratory occasions. Sweet (glutinous) rice and partially cooked adzuki-bean cooking liquid is used to add a red hue to the rice. As adzuki beans tend to break in half when cooking and bring up the image of hara-kiri (ritual suicide), the firmer sasage (black-eyed beans) are sometimes used as a substitute.（意訳：赤飯とはあずきを煮汁と一緒にもち米と混ぜて蒸した飯のこと．祝い事があったときに食べる．あずきは煮くずれしやすいので，「腹がきれる」といって避け，ささげを用いる場合もある）

赤飯を炊く
