<P> 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 . </P>
