Shamrock Shake Bags
Main Tag:
Description: The Shamrock Shake, a cult-classic mint-flavored green fast food milkshake, was created by a Connecticut franchisee in 1967 to celebrate St. Patrick's Day. It was a such a hit that word got back to corporate, and just a few years later, it debuted nationally. While famous today for its mint flavor, the shake originally used a lemon-lime sherbet blended with vanilla soft serve. By 1973, it was changed to a plain vanilla shake with green dye, before adopting the green mint-flavored syrup everyone knows and loves. Beginning in 1975, the shakes were promoted by a character named Uncle O'Grimacey, but in 1979, he got the boot in favor of a group of leprechauns like those we see here.
