As with everything at Shake Shack—the ShackBurger, the milk shakes—the custard has a cultish following. Since flavors change month to month, here's a new Chowhound thread devoted to the glory of the February offerings (and hey, major props to fellow fans of frozen treats in frozen weather).
This is turning into the ultimate custard thread, with hounds goading one another to try each of the daily specialties, from the Bee Mine (a rose-honey-strawberry concoction) to the Snowball (coconut custard alert!) to Bananas Foster. The Thin Mint is what has us obsessed, although we haven't yet tried it. Thanks to tpigeon for getting everyone all riled up, and to the hounds for howling their expertise.
