I've just watched
Rick Stein and the Japanese Ambassador on BBC2 to see the pescatorian publicist eulogise about Japanese cuisine on a fishing trip to Japan. He was trying to learn how to prepare sushi properly after being reprimanded by his efforts by the ambassador.
Apparently, the Japanese seek to create dishes in 5 colours - blue, green, yellow as well as red and white (the colours in their national flag).
He then supervised 2 Japanese embassy chefs who produced an 8-course banquet for the Japanese ambassador to the
Court of St. James's, including the traditional 2nd course soup and a radish sliced and diced into the shape of a butterfly.
