Many Irish immigrants settled in the Southern U.S. (including my family) - much of the cuisine reflects this. Also, many cultures have versions of "potato pancakes."
I guess I must really be Irish because I've never met a potato dish I didn't like! I even love 'em plain - cold, boiled.
The boxty is particularly versatile - served plain with butter, topped or filled & rolled with numerous variations of sausage, bacon, eggs, cheese, meats, poultry, fish, vegetables, & sauces. I've had many of these - all DELICIOUS! I've always had savory versions, but I bet they'd be terrific "blintz-style" (filled/topped with cheese/fruit/sauce, too!
Happy Saint Patrick's Day!
