Bettara duke is Japanese famous sweet Daikon pickles.
If you have Ama koji (Sweet koji), you can make it at home easily.
It is nicely naturally sweet !
This is how to make Bettara-duke. (べったら漬け）
When water comes to the top, then you can take Daikon out from container.
Now use Ama-koji (Sweet Koji) as pickling sauce.
Pour prepared Ama-koji into container. (Or you can get Ama-koji from Asian shops)
(This time, I added little bit of Mirin, that is why this pickling sauce looks little bit brown)
Then put the Daikon into the pickling sauce.
In this pickling sauce, you can add chili or Konbu for more deep taste.
