Many of the customs and beliefs associated with St. Patrick's Day originated in countries other than Ireland, especially the United States. Many of the traditions connected with
St. Patrick's Day celebrations in the U.S. are associated with either Irish-American folklore or with consumer marketing. This extends to some of the most popular St. Patrick's Day recipes, such as
corned beef and cabbage, which originated in the U.S. and have no association with the
traditional Irish recipes served on that day.
