Dining Outside the Home: Key Lime Pie Bakery! Key limes are as popular in the Florida Keys as conch shells on the beach. If you’ve never tasted one, imagine this: Key limes are more aromatic as well as a bit smaller than regular limes, thus making them less acidic and more tart. By adding sugar, eggs, and a graham cracker crust, the results are a tangy, sweet, light, and creamy dessert that may or may not cry out for a delicious dollop of whipped cream. Merengue is definitely not out of the question either. Drop in for a single slice or an entire pie. It’s convenient enough to make a second trip.
