Ingredients for america's test kitchen double pie crust

Twelve ingredients transform into America's Test Kitchen's legendary flaky double crust—crisp all night long.

The butter is non-negotiable here—cold, cubed pieces create those signature steam pockets for flakiness. European-style unsalted butter (like Plugrá or Land O'Lakes) has higher fat content, which is ideal. If you're in a pinch, store-brand unsalted butter works fine, but let it sit in the fridge for 30 minutes before using. The flour should be sifted—this prevents lumps and ensures even distribution of salt and sugar. For the best results, purchase flour from King Arthur or Bob's Red Mill, as their milling process yields a more consistent texture. Store your flour in the freezer to maintain freshness, especially if you're not using it frequently.

No heavy cream? Cold whole milk works in a bind, though the egg wash won't be as glossy. The egg wash is optional but recommended—it adds a golden finish and subtle richness. For the foil-sealing technique, heavy-duty aluminum foil is critical; regular foil may tear. If you don't have pie weights, dried beans or even pennies will work for blind baking. The sugar and salt should be finely ground—coarse salt or sugar crystals will disrupt the crust's texture. For a nutty flavor, replace 1 tablespoon of flour with all-purpose white flour (though the recipe is already optimized for flakiness).

The dough must rest for at least 2 hours in the fridge—this is non-negotiable for flakiness. Wrap it tightly in plastic wrap to prevent drying. Leftover dough can be frozen for up to 3 months; thaw in the fridge overnight before rolling. The foil-sealed crust stays fresh for 2 days at room temperature, making it perfect for overnight baking. For best results, blind-bake the bottom crust for 15 minutes before adding fillings—this ensures a crisp base even with juicy toppings. Store unused foil in a dry place to prevent rusting.

Step-by-step instructions for america's Test Kitchen double pie crust

Master this foolproof technique for a double crust that stays flaky through even the longest baking times.

In a large mixing bowl, combine the 4 cups All-Purpose Flour, 1 tsp Diamond Crystal Kosher Salt, and 1 tbsp Granulated Sugar. Whisk to evenly distribute the dry ingredients—this ensures consistent flavor and texture throughout the crust.

Cut the 1 cup Unsalted Butter into ½-inch cubes and add to the flour mixture. Using a pastry cutter or your fingers, work the butter into the flour until you achieve pea-sized crumbs with some larger butter pieces remaining. This cold butter creates flaky layers when baked. If using your fingers, keep the mixture cold by chilling the bowl between work sessions.

Add the 0.5 cup Ice Water gradually, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together. Avoid overmixing—just until the dough forms a shaggy mass that holds when pressed. This precise hydration is critical for a tender yet sturdy crust.

Turn the dough onto a lightly floured surface and divide it into two equal portions. Shape each portion into a disk about 1-inch thick. Wrap each disk tightly in plastic wrap and refrigerate for at least 1 hour or up to 2 days. This long chill time is essential for developing maximum flakiness through proper gluten relaxation.

Here's the secret: the cold butter needs time to firm up completely. If you skip this step, the butter will melt too quickly during baking, resulting in a tough crust instead of the delicate layers we're after. I like to place the dough disks on a baking sheet before wrapping to maintain their shape during chilling.

Preheat your oven to 375°F. On a lightly floured surface, roll out one dough disk to fit your pie dish, about 1/8-inch thick. Transfer to a 9-inch pie dish dusted with 0.5 cup Cornmeal—this prevents sticking and adds a subtle crunch. Trim excess dough, leaving a ½-inch overhang. Fold the overhang under itself and crimp decoratively using your fingers or a fork.

For the top crust, roll out the second disk to the same thickness. Brush the bottom crust with the egg wash (beat the 1 whole Large Eggs with 0.25 cup Heavy Cream, 0.5 tsp Vanilla Extract, and 0.25 tsp Freshly Ground Black Pepper). This creates a golden, flavorful finish. Cut slits in the top crust for steam to escape—this prevents a soggy bottom.

Line the bottom crust with the 1 cup Dried Pie Weights or Rice and place the assembled pie on a baking sheet. Cover completely with the 1 sheet Aluminum Foil, sealing the edges tightly to create an airtight chamber. Bake for 25 minutes—this pre-baking step prevents a soggy bottom when filling later.

Remove the foil and weights, then bake for an additional 10-15 minutes until the crust is golden brown and edges are set. The foil trap creates steam that develops the flaky layers while keeping the crust tender. For extra insurance, I sometimes brush the edges with more egg wash before the final baking to ensure they brown beautifully.

Let the pie cool completely before filling—this prevents the crust from becoming soggy when hot fillings are added. The crust should be completely set but still retain its flaky texture. Store any unused dough, wrapped tightly, in the refrigerator for up to 2 days or freeze for up to 1 month.

This double crust technique works perfectly for both sweet and savory pies. The key to maintaining flakiness lies in the cold butter and proper chilling times—never rush these steps. When assembled correctly, this crust will hold its shape and flaky texture even after hours in the oven.

Classic Apple Butter

This homemade apple butter is perfect for spreading on warm pie crusts or using as a filling. Cook 6 cups peeled, chopped apples (like Granny Smith or Honeycrisp) with ½ cup brown sugar, 1 tsp cinnamon, and ¼ cup apple cider in a saucepan.

Simmer uncovered for 45-60 minutes, stirring occasionally, until thick and spreadable. The caramelized sweetness pairs beautifully with the flaky crust, especially in classic apple pies. Store in an airtight container for up to 1 month.

Creamy Vanilla Pastry Cream

For a rich, custardy filling, this pastry cream elevates your double crust to restaurant-quality. Whisk 2 cups whole milk, ½ cup heavy cream, 4 egg yolks, ⅓ cup granulated sugar, 3 tbsp cornstarch, and 1 tsp vanilla extract in a saucepan.

Cook over medium heat, stirring constantly, until thickened (10-12 minutes). Chill completely before assembling. The vanilla and cornstarch create a silky texture that contrasts perfectly with the crust’s flakiness.

Spiced Pumpkin Filling

Autumn calls for this warm pumpkin filling, which balances the crust’s buttery richness. Mix 1½ cups pumpkin puree, ½ cup brown sugar, 1 egg, ½ cup evaporated milk, 1 tsp cinnamon, ½ tsp ginger, ¼ tsp cloves, and a pinch of salt.

Bake the assembled pie at 375°F for 45-50 minutes until the filling is set. The spices complement the crust’s buttery layers, creating a cohesive flavor profile.

Savory Herb Cheese Filling

Transform your double crust into a savory quiche with this herb cheese filling. Whisk 6 eggs, 1 cup heavy cream, 1 cup shredded Gruyère, ½ cup grated Parmesan, 2 tbsp chopped chives, 1 tbsp chopped thyme, and ½ tsp black pepper.

Pour into the pre-baked crust and bake at 350°F for 40-45 minutes until set. The herbs add freshness, while the melted cheese binds the crust’s flaky layers into a cohesive bite.

Lemon Curd Topping

Brighten your pie with this zesty lemon curd, which cuts through the crust’s richness. Cook ½ cup lemon juice, ½ cup sugar, 3 tbsp butter, and 2 egg yolks in a double boiler until thickened (8-10 minutes).

Strain and chill before spreading between the crust layers or drizzling on top. The acidity enhances the crust’s buttery notes, creating a balanced flavor.

Caramel Drizzle Finish

Add a luxurious touch with a salted caramel drizzle. Heat 1 cup granulated sugar in a saucepan until melted, then whisk in ¼ cup heavy cream and 2 tbsp butter.

Simmer for 3-4 minutes until thickened, then drizzle over the assembled pie before baking. The caramel’s sweetness caramelizes beautifully against the crust’s golden edges, adding a professional finish. 🍯
