I saw this at Marukai yesterday. I knew that it was sake lees (a byproduct of sake production) and is used to make tsukemono. I stood in front of it for awhile remembering a few Japanese programs that I'd watched before where they show how some households have a kasu-filled vat in a corner somewhere, and anytime they needed tsukemono they would go to it and dig out a pickled vegetable. I think that's so cool. I wanted to try. This bag was $4.29.
This daikon ($1.49) is actually not as big and obscene-looking as it appears.
Lahaina Baby Eggplant ($3.87)
Keiki Cucumber ($3.99)
Now, I gotta figure out how to do this. Wish me luck! LOL!
