Radish and daikon
Radish and daikon are the crisp, peppery roots, leaves and seed pods of Raphanus sativus, fermented as kimchi, takuan and sinki and eaten raw across Asia and Europe.
Modern method
Takuan (rice-bran fermented daikon)
沢庵漬け (takuan-zuke)
Daikon is dried until pliable, then layered in seasoned rice bran and pressed for a long fermentation.
History
