This is essentially a no-bake, easy, tasty pie made with key limes. I am told that it is not real key lime pie, even though it is made with real key limes (called limones in Mexico where i learned the recipe.)
It has real calories and will make you real fat. It gets real runny at room temperature. But it is imaginary. If anyone has a recipe for REAL key lime pie, feel free to send it along.
Go ahead and buy a graham cracker crust, or make one if you want a real crust on an imaginary pie. You do that by crumbling and pressing graham crackers into a pie tin.
Mix a can of condensed milk (you can use any kind, but for many people, Carnation is the only real condensed milk) together with a can of evaporated milk. Stir in a third of a cup of real key lime juice (not to be confused with ReaLemon or ReaLime juices, which are registered trade marks.) Pour the mixture into your crust and refrigerate for a couple hours or so until it has set. That's it. Now imagine eating it.
