I have heard that Japanese furikake is now booming overseas.
Furikake is a dry Japanese condiment sprinkled on top of cooked rice and so on, according to Wikipedia.
We usually eat boiled rice, which has no particular taste. To improve appetite as well as to add nutrition, the Japanese used to sprinkle various kinds of fragmented foods, such as processed fish, sesame seeds, chopped seaweed, as well as condiments like sugar and salt.
When I was a child, sesame seeds and salt; shaved and seasoned dried bonito (tsukudani); processed small fish or seaweed and the like were popular.
As freeze-drying techniques have developed, various kinds of foods are freeze-dried, such as barbecued meats.
Today, we have wide variety of furikake, and I have heard that Western people get some furikake as souvenirs.
Furikake is useful not only for rice but for pastas, sandwiches, fried potatoes and so on.
