Irish potato candy is a popular Philadelphia confection that is especially popular around St. Patrick's Day. During the 18th century, city taverns such as the London Coffee House and Tun Tavern (birthplace of the United States Marine Corps in 1775) were regular meeting places for the political and business leaders.
