I have never been to Ireland and unfortunately never would be able to go because I am highly allergic to potato's and would not eat pig's feet either.
But, you may love it, so let's see what the Irish eat today.
BoxtyA Boxty is a potato pancake made from fine grating of the potato, providing a smoother consistency than other varieties of potato pancakes.
Bacon & Cabbage
Perhaps the best known of Ireland's traditional dishes, bacon and cabbage is often referred to simply as cabbage stew. Typically, you boil the bacon with cabbage and potatoes, resulting in a flavorful and filling dish. Note that the bacon is served in slabs more like Canadian bacon that that found in the US.
By combining two Irish favorites, potatoes and cabbage, and adding other seasoning, you get a creamy starch called Colcannon.
It is said that the Irish eat this mixture on Halloween. Parents even hide coins inside the dish for children to find. The tradition is for a blindfolded single woman to be led to the cabbage patch to select a head of cabbage for the dish. The characteristics of the cabbage she chose were said to be those of her future husband. I guess the women consider Irish men to be real cabbage-heads.
Crubeens or crunchy pig"s feet
Crunchy pig's feet are widely sold in Ireland as bar or street food. This messy dish is the preferred accompaniment to a pint of beer in many parts of the country, and has experienced a resurgence of popularly. This dish looks awful to me. I would never eat pig's feet but some people in Ireland love it.
Homemade Corned Beef with Vegetables
Here the traditional Irish meal of corned beef and cabbage, served in the US on St. Patrick's day. In the photo it is supplemented with turnips, Brussels sprouts, carrots, and boiled potatoes, an upscale version of the Irish home meal. It is often served with Irish Soda Bread.
So, here they are and hope if you go you enjoy the food.
