There are many cultural challenges to preparing dishes / foods for one particular culture or group.
American Thanksgiving Dinner is a great example.
The basic menu is pretty bland and awful - but quite easy to prepare.
A cruise line typically has a European Corporate Chef, giving instructions to an Asian, European, or Indian Executive Chef, who then instructs a Galley brigade of Filipinos, Indians, and a few Europeans, on how to prepare the Classic American Thanksgiving Dinner Menu. The result is usually quite good, but many pax are shocked when it does not exactly resemble last year's Thanksgiving Menu at Aunt Mary's Farm in Ohio.
I have the same problem with Sushi and Sashimi.
I live in Japan part of the year and really love Japanese food.
When I go on a cruise, I always look for good Japanese Food onboard.
In 40 years of cruising, I have NEVER tasted good Japanese Food on a Western Cruise Ship.
Same problem with Japanese Food outside Japan.
Let's not even talk about Europe. Japanese food there is disgusting.
I frequently visit the USA on business. My colleagues there always want to take me to their latest find of a Great Japanese Restaurant. I am always disappointed. Occasionally in California or Hawaii, I am able to find Japanese Food that is just OK - but never Great. They just cannot manage to match the quality and style of Japan.
