A shake made of Guinness-Milk Chocolate (yes, as in the Irish beer) Ice Cream. Once the ice cream is made one does not taste the Guinness. I suspect it functions to amplify the gorgeous taste of the milk chocolate. It is a softer, silkier consistency ice cream I imagine from the alcohol affecting the freezing. The sides of the glass were drizzled with Fudge Ripple sauce (also from The Perfect Scoop) before adding the shake. Perfect flavors.
