I'll show you some Japanese traditional cuisine in this entry. Do you know a fish named the Japanese horse mackerel? We dropped in at a restaurant near my family graves. The picture was shot at that time.
There are several methods for preparing the fish. The picture shows the preparation called "arai". The dish looks like "sashimi" which is well-known globally, but it isn't "sashimi". Have you ever heard of "arai"? If you are interested in it, look for the recipe on the internet. You have to use the live fish and need hot water in the preparation of "arai".
