にょきにょき生えた茶色のかたまりは雪に埋もれて冬を越した白菜です。
見た目は悪いけど、外側の茶色い葉をとれば中身は真っ白。
冬の間、葉のでんぷんを糖分に変えて生き延びた甘くてとろけるような霜降りの白菜。
冷蔵庫がない時代からの先人の知恵です。
A brown lump is a Chinese cabaret buried in the snow and crossed the winter.
It looks bad, but if you take the outer brown leaves the contents are pure white.
Sweet and mellowish marbling cabbage survived by converting leaf starch to sugar during winter.
It is wisdom of the predecessor from times when there is no refrigerator.
