The key to a Key West Key Lime Pie is the lime. Key limes are sweeter and less acidic, providing the perfect balance of flavor for the sweet and creamy filling. But of course, Key West Key Lime Pie isn't all about the lime; it's also about the buttery, crumbly graham cracker crust and the fluffy, refreshing, and homemade whipped cream dolloped onto each slice. Think of Key West Key Lime Pie like a trip to the beach: you need the sun, sure, but you also need the cool surf and the white sands beneath your feet. With just a bite, your tastebuds are going on a beach trip!
