Girlfriend Fay gave me some takuan when I went to shoot her granddaughter Ailey's pictures. I really liked it so I asked her for the recipe. Looks pretty easy to make. Not sure what "Korean" daikon is though.
7-8 lbs Korean daikon
Boil: 9 T. salt 4 c. sugar 1-1/2 c. Japanese vinegar 1-1/2 t. yellow food coloring
Chili pepper flakes (optional)
Cut daikon into desired pieces. After mixture comes to a boil, pour over daikon pieces. Cool then refrigerate.
