Over the course of the summer, Business Insider’s Gabbi Shaw embarked on a grueling mission: to taste and rank every shake on Shake Shack's menu. Just as she was getting her appetite for shakes back, the chain announced three new holiday flavors — so she knew what she had to do. It was time to revisit the shake rankings. The 14 flavors, which are each made with frozen custard, include classics such as chocolate and vanilla, and limited-edition shakes, such as the Dubai Chocolate Pistachio shake, which was available over the summer. On November 18, the chain released three holiday flavors: a Christmas Cookie Shake, a Sticky Toffee Pudding Shake, and a Peppermint Bark Chocolate Shake. See how Shaw ranked them all, from her least favorite to her favorite, at the link in our bio. Story by Gabbi Shaw (Credit: Gabbi Shaw/Business Insider) #shakeshack #shakes #fastfood
