Ingredients for america's test kitchen double pie crust

Precision-calibrated ingredients for the ultimate flaky double pie crust—no shortcuts.

The butter is non-negotiable—use European-style unsalted butter like Plugrá or Land O'Lakes for optimal fat content. Purchase it in bulk from Whole Foods or Costco to ensure consistent quality. The flour should be bread flour if available, but all-purpose works fine. Sift it thoroughly to eliminate lumps, which disrupt the delicate layering. For the ice water, freeze it overnight in ice cube trays for maximum chill. The kosher salt is essential for flavor balance, and Diamond Crystal is preferred due to its finer grain compared to Morton's.

No European-style butter? Use regular unsalted butter, but chill it longer to compensate. Short on vinegar? Lemon juice works at double the amount. The egg yolk can be replaced with 1 tbsp milk plus 1/2 tsp mustard for egg-free binding. For the cornmeal, semolina or all-purpose flour are suitable substitutes. The sugar can be omitted entirely if you prefer a neutral flavor profile. When handling the dough, use cold hands to prevent melting the butter prematurely—this is critical for achieving those signature flaky layers.

Store the dough between parchment paper in an airtight container for up to 2 days in the refrigerator. For longer storage, wrap tightly in plastic and freeze for up to 3 months. Thaw overnight in the fridge before rolling. The butter pieces should remain distinct when mixed—this ensures proper flakiness. If the dough becomes too warm during handling, return it to the fridge for 15 minutes before proceeding. Pre-chill all tools, including rolling pins, to maintain cold temperatures throughout the process.

Step-by-step instructions for america's test kitchen double pie crust recipe

A methodical approach ensures two perfectly flaky, tender crusts every time—no shrinking, no cracking.

In a large mixing bowl, combine the 4 cups all-purpose flour, 0.5 teaspoon diamond crystal kosher salt, and 1 tablespoon granulated sugar. Whisk to evenly distribute the dry ingredients—this prevents pockets of salt or sugar that can create uneven texture. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers, working quickly to distribute the butter into pea-sized pieces throughout the flour. The butter should remain cold; if it starts to melt, chill the mixture for 10 minutes before proceeding.

Create a well in the center and add the 1 whole large egg yolk, 1 tablespoon white vinegar, and 0.33 cup ice water. Using a fork, gently mix just until the dough begins to come together—overmixing develops gluten, which leads to toughness. The dough should be shaggy but hold when pressed. If it crumbles excessively, add 1 teaspoon ice water at a time until it forms a cohesive mass.

Divide the dough into two equal portions, flatten each into a disk, and wrap tightly in plastic wrap. Refrigerate for at least 1 hour—this critical step allows the gluten to relax and the butter to firm up, ensuring clean layers when rolled. For best results, chill overnight; the longer the rest, the more tender the final crust.

After chilling, dust a clean surface with 2 tablespoons yellow cornmeal to prevent sticking. Working with one disk at a time, roll the dough into a 12-inch circle, about ⅛-inch thick. The edges should be slightly thicker than the center to prevent shrinking during baking. If the dough resists rolling, let it rest at room temperature for 5 minutes before attempting again.

Preheat the oven to 375°F. Transfer the rolled crust to a 9-inch pie dish, gently pressing it into the edges to create a snug fit. Line the crust with parchment paper, fill with pie weights or dried beans, and bake for 15 minutes. This pre-baking step, called blind-baking, prevents a soggy bottom when filling the pie later. Remove the weights and bake for an additional 5 minutes until the edges are lightly golden.

While the bottom crust bakes, repeat the rolling process with the second dough disk. This second crust will serve as the top layer, so roll it slightly thinner—about ⅛-inch to ¼-inch thick—to ensure even coverage. Keep it chilled until ready to assemble the pie.

Once the bottom crust is partially baked, carefully remove it from the oven and reduce the heat to 350°F. Add your pie filling, then drape the second crust over the top, trimming excess dough with a sharp knife. Crimp the edges using a fork or your fingers to seal the pie. Cut 4-5 slits in the top crust to allow steam to escape—this prevents a burst crust during baking.

Bake the assembled pie for 45-55 minutes, or until the top crust is deep golden brown and the filling is bubbling at the edges. For extra shine, brush the top crust with a beaten egg white mixed with 1 teaspoon water before baking. The crust should be flaky, with crisp edges and a tender, melt-in-your-mouth texture throughout.

Allow the pie to cool for at least 2 hours before slicing. This resting period lets the filling set and the crust firm up, ensuring clean slices with maximum flakiness. Serve at room temperature for the best texture—cold crusts lose their tenderness, while warm pies risk a soggy bottom.

The key to success lies in the butter's temperature and the dough's rest time. Cold butter creates steam pockets during baking, while proper chilling relaxes the gluten for that signature flaky, layered texture. Follow these steps precisely, and you’ll achieve a crust so tender it nearly dissolves in your mouth.

Common mistakes when making your america's test kitchen double pie crust

Overmixing the Dough

This is the #1 mistake that turns flaky crusts into tough, chewy messes. When you mix the dough too much, gluten develops rapidly, creating a dense texture instead of delicate layers.

I’ve seen home bakers use stand mixers or overwork the dough with their hands, thinking more mixing equals better results. The secret is to stop mixing as soon as the dough just holds together—it should look shaggy, not smooth. Use a fork and work quickly to avoid overhandling. 💡

Skipping Chill Times

Rushing the chilling steps is a fast track to disappointment. Whether you skip the initial 1-hour chill after shaping or forget to let the dough rest between rolling, you’ll end up with a crust that shrinks or cracks.

The cold butter needs time to firm up, and the gluten must relax to create those signature flaky layers. I’ve learned the hard way—once, I baked a pie without proper chilling, and the crust turned into a sad, dense pancake. Plan ahead and chill overnight if possible.

Using Warm Butter

Room-temperature butter is the enemy of flakiness. When butter melts too early, it creates steam pockets that evaporate before baking, leaving no layers behind. Always use butter straight from the fridge, cubed into ½-inch pieces.

If your kitchen is warm, chill the butter for an extra 10 minutes before cutting it into the flour. I keep my butter in the freezer for 15 minutes when working in hot kitchens—this ensures it stays cold throughout mixing.

Uneven Rolling Thickness

Inconsistent thickness leads to uneven baking—some parts crisp up too fast while others stay doughy. Aim for a uniform ⅛-inch thickness for the bottom crust and ⅛-inch to ¼-inch for the top. The edges should be slightly thicker to prevent shrinking.

I use a rolling pin with measurements marked on the handle to check thickness as I roll. If the dough resists, let it rest for 5 minutes at room temperature before continuing.

Overfilling the Pie

Stuffing a pie with too much filling can cause the crust to burst or leak. The filling should fill the crust about ¾ full—any more risks overflow during baking.

If you’re making a deep-dish pie, use a 9-inch pie dish and fill it to the rim with the crust edges folded inward. I’ve seen pies explode in the oven because of overfilling, so measure your filling carefully.

For runny fillings like berry compotes, pre-bake the bottom crust longer to create a stronger barrier.

Ignoring Venting Slits

Forgetting to cut steam vents in the top crust is a surefire way to end up with a burst pie. Those 4-5 small slits let steam escape, preventing pressure buildup that can cause the crust to crack or puff up unevenly.

I like to make the slits with a sharp knife or pizza wheel—just enough to release steam without letting filling escape. Skipping this step is especially risky with high-moisture fillings like apple or berry pies. 🌟
