Wikipedia: Shamrock Shake
The Shamrock Shake is a seasonal green-dyed mint flavored milkshake dessert sold at McDonald’s to celebrate St. Patrick’s Day.
 
Origin
The Shamrock Shake was first introduced in 1970. Rogers Merchandising in Chicago created the shake. Initially, the shake was lemon/lime flavored with vanilla ice cream, lemon/lime sherbet, and vanilla syrup. By 1973, the shake was merely a green colored vanilla shake, eliminating the lemon/lime sherbet. It is now mint flavored.
