Rakkyo, takuan, & tsukemono If you ever go to a depachika, the bottom floors of a department store, you'll notice that samples of products are sometimes offered. One kind of sample offered is the pickled vegetables. Since I am partial to onions, I love to sample the rakkyo, which are like sweet sour pearl onions. Another favorite is takuan, made of daikon, as well as tsukemono, made of cabbages, etc. These make great side dishes for a bowl of rice and a piece of grilled meat or fish. Add a bowl of miso soup and it becomes a complete meal, fit for a hardworking samurai.
