Tekka
Tekka is the name for a certain miso-condiment that consists of a number of root vegetables (Greater
Burdock roots,
carrots,
Ginger root, and Lotus root) which have been stir-fried and boiled to a concentrated powder. Traditional preparation time used to be 16 hours (on a low fire), yet speedier preparation is possible.
