Key lime pie is a dessert that I have been in love with since I was a teenager. It is such an easy to make dessert and a frequent request of mine. I have a buddy that I make this dessert for him for his birthday every year. It is one of his favorite desserts.
In this recipe
One of the best parts of the key lime pies is the filling is usually only three things: key limes, condensed milk, and egg yolks. This recipe packs an added key lime punch with the addition of the zest of the limes as well. It takes about 30-40 key limes to make produce the needed juice. You can also buy key lime juice but make sure it is not from concentrate. I prefer to use fresh lime juice if at all possible.
Making the key lime pie
When zesting the limes it is easier to do this before since they are so small. You will need the zest of about 10 limes to get all of the zest that you will need for the pie. Also at once the pie has been cooled and set add a little more zest for a little pop of color. With the lime juice and zest ready quickly whisk all of the ingredients to pour into the prepared crust.
Preparing the crust
In order to get a nice even crust a flat bottomed object with angles similar to the pie pan will help. If you have two of the same pie pans then that the best to get a nice and even crust. One of the other things to consider is to make sure that the crust cools before adding the filling. This will help with making sure the pie bakes evenly.
Checking for a wobble
Like cheesecake you will want to make sure that the filling is not completely set when you remove it from the oven. An easy way to tell is if the middle of the pie will wobble like Jell-O when the side of the pie is tapped. Then once removed allow it to come to room temperature before cooling in the refrigerator. This will keep the pie from splitting once it cols down. Also it is important to wait at least 2 hours for the pie to completely set.
