Dennys Food and Recipes: Easy and Simple: How To Make The Best Key Lime Pie: "From Denny: Making your own key lime pie is so simple - and rewarding! It's definitely one of my favorite desserts, especially in the heat of the summer. The tartness really cools you off. FYI, any tart food cools down your liver, which, in turn, cools off your body in hot weather. So, think apples, limes, grapefruit and blackberries if you want to cool off the healthy way.
Florida is known for their key lime pie and there are fans of it all over the country now. The real secret to making this simple and easy famous pie is to purchase real key limes for the recipe. Key limes are very small, very tart and thin-skinned. When ripe they turn from green to yellow.
Most limes in our American grocery stores are those large beautiful, neon green and thicker-skinned Persian limes. Persian limes are also much less tart so they don't deliver that full flavor to the pie cooks, and tasters alike, desire.
How simple is this pie recipe? Really simple: 100 percent key lime juice, sweetened condensed milk and a good graham cracker crust with a little melted butter, brown sugar and chopped nuts. At our house we make the chocolate graham cracker crust while others choose to use traditional pastry crust. It's your preference."
