I made this rice dish for a family gathering that included some people who preferred brown rice and others who were adamently against it.

The Yin is brown rice, with brown mushrooms and onion sauteed in olive oil. The Yang is white rice with leeks and celery sauteed in safflower oil. Both are seasoned with salt, and the brown rice with pepper as well. The garnishes are a whole mushroom and a pearl onion, boiled.

Each half tastes good on its own, and they also taste good mixed together. (As one would hope!)

Filling in the "tails" gives you the classic symbol:

Set up the pattern starting at the very bottom of the bowl, and slowly build it up until the bowl is full.
