Due to the food situation after war the supply of green onions varied from one season to another and instead of this, cabbage which was cheap and available through the year came to be used (in later years bean sprouts were also used).
戦後の食料事情により、季節により供給量が左右されるネギを、単価が安く年間通して手に入りやすいキャベツに変えた（もやしは後年入れられる事になる）。
