Got milk? They didn't have much of it in the Keys prior to the railroad opening in 1912, so when Gail Borden created sweetened condensed milk in 1859, the isolated residents rejoiced — they could finally invent key lime pie! They didn't even need to bake the pies, for the acidity of the limes curdled the condensed milk and egg yolks to form a smooth consistency. Think of how much trouble they saved by not having to haul cows and ovens in from the mainland! Nowadays it's even easier to enjoy Florida's most famous dessert, because it is sold and served just about everywhere in the state. Finding a captivating rendition, however, can be difficult. We say search no further than Bonefish Grill in Coral Gables, a "casual-upscale" seafood chain that proffers fresh fish dinners at affordable prices. Their sumptuous pies' crusts are traditional graham cracker, but with crunchy pecans; a dollop of freshly whipped cream luxuriates on top. Between those contrasting textures is a tall, pale cloud of tart, creamy custard — bigger and better than others of its ilk, and at $5.50 per hunky wedge, cheap.
