In the last few Cooking Tips, we have been discussing how to put that perfect pie on your holiday table. We looked at ingredients and techniques for making a great pie crust. You are now ready to put it in the oven but there is another subject to discuss – blind baking your pie crust. That is the subject of this Cooking Tip.
Blind baking a pie crust is simply pre-baking your crust (either partially or totally) before adding your filling. So, when do you blind bake your crust? The simple answer you might say is – when the recipe tells you to do so. Yes, that is true, but there are general guidelines to let you know whether you should do this.
Pies that have fillings that are not baked require a fully baked pie crust. An example is a yummy French Silk Pie. Since the pie is not going into the oven after adding the filling, the pie crust needs to be fully baked.
Other times you want to blind bake is with custard pies or pies with delicate fillings. With custard pies (such as pumpkin), the moisture in the filling might make the crust soggy before the crust is fully baked. Partially baking the crust before adding the filling helps to prevent this. There are also some delicate fillings that are only briefly cooked on the stovetop. If you do not blind bake the crust but rather put the filling in an unbaked crust, the filling would be over-cooked before the crust is fully baked. An example is Chocolate Cream pie.
One time you do not want to blind bake is if you are making a double-crust pie. If you blind bake the bottom crust, your top crust won’t adhere to the bottom crust. If your filling is such that you would prefer a blind-baked crust to prevent sogginess, you can place decorative pieces of crust over the top to give you a type of open double crust such as in this Gooseberry Pie recipe.
Blind baking is not as simple as putting your unfilled pie crust in the oven. If you do that without adding some weight, your pie crust will puff up – not ideal if you want to put a delicious filing into it. It also makes it much more likely that the sides of your crust will droop before it sets.
Now we know why we need to blind bake a crust, how do we do it? There are three recommended ways depending on what you are looking for in your finished pie.
If you want a pie with a pretty crimped edge or you have a tall crust, line the unbaked crust with foil or parchment making sure it fully covers the crust and the edges of the pie crust. Foil is often preferred over parchment as you can get it into the corners better as well as folding over the crust to prevent overbrowning. Fill the crust at least 2/3 full with something to weight the crust down as it bakes. I love ceramic pie weights. They conduct heat well and fill up the entire crust. Just make sure you have enough to fully cover the crust. I tend to use two boxes of these for one pie crust.
You have probably heard that you can use dry beans or rice. Those are poor heat conductors resulting in a longer baking time to get to the proper stage. Another option is granulated sugar, an excellent heat conductor.
Stacey Ballis with MyRecipes.com did an experiment testing different types of weights. Her favorite method was granulated sugar, which conducts heat as well as the ceramic weights but gets into the corners of the pie crust better. She uses the sugar a couple of times and then uses it in her baking. Since it has slightly caramelized by being in the oven, she recommends using it for meringues. SeriousEats.com agrees with this choice. If you don’t want to use sugar, the ceramic weights are a close second.
As I discussed in last week’s Tip, you should have chilled your pie crust. If you haven’t done that by this step, you may chill it with the weights in place. After chilling, place it in a 375° oven for 20 minutes. Remove from oven and carefully remove the very hot pie weights. Prick the bottom with a fork and return crust to the oven. If you will be baking the pie filling, bake the crust for another 5-8 minutes. If you are not baking the filling, bake the crust for another 12-20 minutes until fully baked. This method should work for most pie crusts but some recipes may have slightly different baking temperatures and times.
A second method is called the “Low & Slow” method. With this method, the pie crust is baked at 350° with pie weights in place for an hour. Baking at a more moderate heat is said to reduce shrinkage & puffing.
A third method is to sandwich the crust between two pans and bake upside down. This method is good for pies with a flat edge that do not need the extra height or when you are not looking for a decorative edge. To use this method, place the crust in the pan and flatten its edge. Spray the outside of another pie pan and nestle into the crust. You may also line the crust with parchment before putting pans together. At this point, chill for 30 minutes to solidify fats and prevent shrinkage.
Now, place the pans upside down on a baking sheet so that the empty pan is on the bottom. Bake for 20 minutes in 375° oven. As the proponents of this method say, “Gravity ensures that as your crust slips “down” the side of the pan, it’s actually moving up!” When baked, remove from the oven and use a spatula to carefully turn over and prick with fork. Return the crust to the oven right side up without second pan and bake for 15-20 minutes until golden brown. You may now fill the crust. When would you want to do this method? It is ideal for pies where the edge of the pie is not as important as its top, such as Lemon Meringue.
What about your pie plate? SeriousEats.com looked at the types of pie plates and recommends either tempered glass or aluminum. They found that ceramic pie plates conduct heat too slowly resulting in more melting of the butter giving you a more mealy and less flaky crust.
Now you have all the information you need to make that beautiful and delicious pie. Get into your kitchen, give the many recommendations a try and let me know what works best for you. And, send me a photo of that wonderful pie!
