Brown Shimeji tend to have a slightly stronger, nuttier flavor, while white Shimeji are generally milder in taste. The Brown Shimeji is mostly a little firmer then the White Shimeji.
Shimeji should always be cooked: it is not a good mushroom to serve raw due to a somewhat bitter taste, but the bitterness disappears completely upon cooking. The cooked mushroom has a pleasant, firm, slightly crunchy texture and a slightly nutty flavor. Cooking also makes this mushroom easier to digest. It works well in stir-fried foods, as well as with wild game or seafood. Also, it can be used in soups, stews, and in sauces.
