From a trip to Japan a friend gave me a mystery jar of some sort of flavoring. It turned out to be wasabi-flavored furikake. Furikake is used to season rice, I learned. It vaguely resembles salt and pepper but is far more complex and powerful. A version I bought has 25 ingredients, including sesame, wheat flour, lactose, salt, MSG, salmon, fish bone powder, and soybean protein. I use it many ways: on roast beef, eggs, and yogurt, for example. It is the easiest way I know to make hamburgers taste good.
The nearest Japanese market (in Berkeley) has 25 different types, I discovered. They cost about $4 each. I bought four. I’m going to buy ten more, to use for crazy spicing (randomly varying the smell of food to prevent strong smell-calorie associations from forming).
