The Shamrock Shake, a green, mint-flavored milkshake, is a seasonal dessert sold at McDonald's during March to celebrate St. Patrick's Day. The Shamrock Shake was first introduced in 1970, and is credited with helping pave the way for other seasonal drinks, including Starbucks Coffee's pumpkin spice and eggnog lattes. The ingredient list for the shamrock shake syrup includes high fructose corn syrup, corn syrup, water, sugar, natural flavor (plant source), xanthan gum, citric acid, sodium benzoate (preservative), yellow 5, blue 1. These are not the same ingredients included in the vanilla shake syrup.
