Well I've been there and I sure did enjoy the seafood. That's not really ethnic influence, but they catch a lot of fish and lobster there. Agriculture is being phased out there as more and more farms are subdivided for second home lots. Sorry I cannot be of more help.

To further answer your question, it's great that you've already identified the influence of the Irish in the culinary culture of Prince Edward Island (P.E.I.) through the focus on potatoes. Now, let's explore some additional cultural influences on foods in P.E.I.

1. Acadian Influence: The Acadian community, which has a rich culinary heritage, also plays a significant role in shaping the food culture of P.E.I. Traditional Acadian dishes, such as rappie pie, fricot (a chicken and potato stew), and poutine râpée, have found their way into the local cuisine.

2. Scottish Influence: P.E.I. has a strong Scottish heritage due to the historic Scottish migration to the province. Scottish cuisine has made its mark through dishes like haggis, black pudding, and Scotch eggs, which can be found in various establishments.

3. English Influence: As part of the British heritage, P.E.I. has been influenced by English cuisine. Classics like fish and chips, bangers and mash, and shepherd's pie have become popular dishes on the island.

4. Indigenous Influence: The indigenous Mi'kmaq people have contributed to the culinary traditions of P.E.I. Certain ingredients and cooking methods, such as wild game, fish, and various foraged foods, have been an integral part of their culture, which has influenced the local cuisine.

5. International Influence: P.E.I.'s culinary scene has also been shaped by global influences. Due to open trade and immigration, the province has welcomed diverse cultures, resulting in the integration of international flavors and dishes into the local food culture. This includes cuisines such as Chinese, Indian, Lebanese, and Thai, which can be found in various restaurants across the island.

Remember, when exploring cultural influences on food, it's helpful to consider historical background, immigration patterns, and the diverse communities that have contributed to the culinary landscape of a region.
