Napolitan spaghetti

Napolitans (ナポリタン), often also referred to as Naporitana, are a dish of spaghetti topped with the ketchup-based sauce that gives it its name.

Although many Japanese believe that this dish has Italian origins, it is actually absolutely Japanese. Probably the Napolitan spaghetti represent the best known and emblematic case of yoshoku cuisine, or that branch of Japanese cuisine that has taken Western dishes as a starting point, has reworked them and made them its own.

The origin of this imaginative dish dates back to the end of the Second World War, during the occupation of Japanese soil by American troops led by General McArthur. The latter, at the time, was a guest at the New Grand Hotel in Yokohama. The chef of the Shigetada Irie hotel, to please the foreign guests, decided to create a recipe that met their tastes and to do so he started from the food rations that the soldiers had with them. The chef didn't use ketchup at first, but canned tomato sauce. The choice to use ketchup was made by the first chef of the hotel restaurant, a Swiss who claimed to know the real Neapolitan tomato sauce. It was the same cook who, by letting them cook much longer than the indicated times, made them overcooked, almost similar to noodles.

Making this dish with ketchup was much easier and cheaper than using tomato sauce. For this reason the recipe was copied and replicated in a short time by numerous restaurateurs who included it in the menu of their premises.

Although Napolitan spaghetti make Italians horrified, in Japan they are very easily found and are an omnipresent preparation especially in family restaurants.
