Shamrock Sandwich

A “shamrock sandwich” is one specialty that is made for St. Patrick’s Day. There appears to be no one recipe for the shamrock sandwich; in every decade, the recipes are different. Vatious green items have appeared in the shamrock sandwiches, such as lettuce, cucumber and celery.
 
The one similarity in all the sandwiches is usually the shamrock shape. A 1921 article explained the shamrock-shape cutter: “This ‘shamrock’ cutter is nothing more or less than the ‘club’ cutter of the sandwich set.” Shamrock sandwiches were shaped similar to the “club” sandwiches (modeled after the “club” card).
 
“Shamrock sandwiches” have been cited in print since at least 1905.
 
 
Wikipedia: St. Patrick’s Day
Saint Patrick’s Day (Irish: Lá Fhéile Pádraig) is a yearly holiday celebrated on 17 March. It is named after Saint Patrick (circa AD 387–461), the most commonly recognized of the patron saints of Ireland. It began as a purely Christian holiday and became an official feast day in the early 1600s. However, it has gradually become more of a secular celebration of Ireland’s culture.
 
It is a public holiday on the island of Ireland; including Northern Ireland and the Republic of Ireland, as well as in Newfoundland and Labrador and in Montserrat. It is also widely celebrated by the Irish diaspora, especially in places such as Great Britain, Canada, the United States, Argentina, Australia, New Zealand, and Montserrat, among others.
 
Wikipedia; Shamrock
The shamrock is a symbol of Ireland. It is a three-leafed old white clover. It is sometimes of the variety Trifolium repens (a white clover, known in Irish as seamair bhán) but today usually Trifolium dubium (a lesser clover, Irish: seamair bhuí).

The diminutive version of the Irish word for “clover” (“seamair”) is “seamróg”, which was anglicised as “shamrock”, representing a close approximation of the original Irish pronunciation. However, other three-leafed plants — such as black medic (Medicago lupulina), red clover (Trifolium pratense), and wood-sorrel (genus Oxalis) — are sometimes designated as shamrocks. The shamrock was traditionally used for its medical properties and was a popular motif in Victorian times.
