Should You Top Fruit Pie Fillings with Butter? | Cook's Illustrated (2024)

FAQs

Why put butter on top of pie filling? ›

The theory is that the fat disrupts the formation of bubbles on the surface of the viscous fruit mixture.

Some maintain that the butter is for taste; others claim that it helps the filling set up, particularly when using flour as a thickener.

Coating the inside surface of the bottom crust will create a barrier to prevent sogginess. Adding a layer of corn syrup or a slightly beaten egg white before pouring in the filling will form a seal between the pie dough and the filling and will help make the crust crisp and flaky.

Butter for flakiness and flavor, and shortening for its high melting point and ability to help the crust hold shape. You can use butter-flavor shortening if desired. If you want to skip the shortening, feel free to try this all-butter pie crust instead.

Pastry chef Cheryl Day offers another alternative: “lining the edges of the pan with a double layer of heavy-duty foil will prevent the pan from heating up too fast and help prevent the cake from doming in the middle.”

Non-stick spray, butter, or shortening in the pie dish, on the other hand, will prevent sticking — but since most pie and tart crusts are pretty heavy on the butter already, you shouldn't need a lot of, if any, grease to get the job done. Using too much, or the wrong kind, can change the texture of your pie dough.

Inconsistent Results. Butter tends to melt faster than other fats when exposed to heat, which can cause problems in certain recipes where precise measurements are key.

Cookies provide a solid example of the differences in using butter or shortening in a recipe. Cookies made with only butter may spread a bit more, have crisper edges and taste rich and buttery. Those made with only shortening bake higher and spread less during baking.

You do not need to pre-bake a pie crust for an apple pie or any baked fruit pie really, but we do freeze the dough to help it stay put. Pre-baking the pie crust is only required when making a custard pie OR when making a fresh fruit pie. you should probably get: Pie weights are super helpful to have for pre-baking.

Sprinkle dried breadcrumbs or crushed cornflakes, or other types of cereal, on the bottom crust before filling and baking in the oven. This will prevent the filling from turning the crust soggy.

How do you make fruit pie not runny? ›

Flour is the only thickener that produces significant cloudiness, though cornstarch-thickened filling is somewhat more opaque than fillings thickened with other starches. Taste-wise, the best thickener is Pie Filling Enhancer.

Cold unsalted butter – Supplies the pie crust's unbeatable flavor and flaky texture. Use unsalted butter. The amount of salt in different brands' salted butter varies, so for better control over the flavor, it's best to begin with unsalted and add your salt.

Butter is prized for its sweet, rich flavor and is our preferred fat for pie crust recipes, but its low melting point and overall makeup can make it difficult to work with. Unlike shortening or lard, butter is not 100% fat.

The cons: Butter can be harder to work with than lard or shortening because of its lower melting point, so the dough temperature has to be just right. If it gets too warm, it will be too soft to handle and will tear easily. Butter is a firmer fat, so if it's too cold, your dough will be more difficult to roll out.

Brushing a bit of melted butter on the rolled crusts can give a nice richness if that's what you're after. In the bowl of a food processor, combine the cookies and the sugar and cinnamon, if using.

My pumpkin pie always cracks or separates from the crust.

The solution? Blind-bake your pie crust with pie weights until light gold, then pour in the filling and bake until inch or so diameter in the center is still jiggly like jello—not soupy.

Cornstarch as Pie Filling Thickener

Just like the name suggests, cornstarch is derived from corn. Cornstarch is faster-acting than flour and forms a smooth, relatively clear filling. Just be aware that too much cornstarch can create a slimy texture.

One frequent question I get is "What does 'dot with butter' mean?" Dot with butter means to literally, place "dots" of butter on top of the filling and under the top crust. This extra step makes the pie's filling a little bit more delicious and rich, but doesn't do much else. Your Grandma did it and you should, too.
