Did Americans introduce western words for forks, spoons and knives?
Perhaps you are starting to wonder what foods exactly the English could have introduced to other countries, but what was actually imported was formal French cuisine with British table manners.
According to this page:
As for dishes, many Western recipes have taken hold in Japan with English names, such as "beef stew" or "beef steak", despite the fact that those introduced via Britain was French in origin, as meals served at royal ceremonies or diplomatic receptions were likewise based on French cuisine even in Britain.
Note that English names of cutlery are associated with Western foods. For example we have traditional Japanese spoons (匙【さじ】) or Chinese soup spoons (蓮華【れんげ】) that are never called スプーン.
