America's Test Kitchen is a real 2,500 square foot test kitchen located just outside of Boston that is home to more than three dozen full-time cooks and product testers. Our mission is simple: to develop the absolute best recipes for all of your favorite foods. To do this, we test each recipe 30, 40, sometimes as many as 70 times, until we arrive at the combination of ingredients, technique, temperature, cooking time, and equipment that yields the best, most foolproof recipe. America’s Test Kitchen's online cooking school is based on nearly 20 years of test kitchen work in our own facility, on the recipes created for Cook's Illustrated and Cook’s Country magazines, and on our two public television cooking shows.
The juiciness of a perfect summer peach is sublime—except when you want to bake it into a pie. To tame the moisture, we macerate the peaches to draw out some of their juices and only add some of the juice back into the filling. We also use both cornstarch and pectin to bind it, because we find that using two thickeners leaves the pie with a clear, silky texture and none of the gumminess or gelatinous texture that larger amounts of either one alone produces.
Making a lattice top for a pie can be intimidating. But it needn’t be if you use our simple technique: Freeze strips of dough and then arrange them in our prescribed order over the filling. Done properly, this approach gives the illusion of a woven lattice with less effort.
Not only does a lattice top look beautiful, making for a great presentation, but it lets the right amount of steam out, ensuring that your pie won’t bubble over or rupture in the oven. And with some tinkering, we found a way to make one that’s easy as, well, pie.
If your peaches are too soft to withstand the pressure of a peeler, cut a shallow X in the bottom of the fruit, blanch them in a pot of simmering water for 15 seconds, and then shock them in a bowl of ice water before peeling. For fruit pectin we recommend both Sure-Jell for Less or No Sugar Needed Recipes and Ball RealFruit Low or No-Sugar Needed Pectin.
3 pounds peaches, peeled, quartered, and pitted, each quarter cut into thirds
1. Toss peaches, 1/2 cup sugar, lemon zest and juice, and salt in medium bowl. Let stand at room temperature for at least 30 minutes or up to 1 hour. Combine pectin, cinnamon, nutmeg, and 2 tablespoons sugar in small bowl and set aside.
2. Remove dough from refrigerator. Before rolling out dough, let it sit on counter to soften slightly, about 10 minutes. Roll 1 disk of dough into 12-inch circle on lightly floured counter. Transfer to parchment paper–lined baking sheet. With pizza wheel, fluted pastry wheel, or paring knife, cut round into ten 1 1/4-inch-wide strips. Freeze strips on sheet until firm, about 30 minutes.
3. Adjust oven rack to lowest position and heat oven to 425 degrees. Roll other disk of dough into 12-inch circle on lightly floured counter. Loosely roll dough around rolling pin and gently unroll it onto 9-inch pie plate, letting excess dough hang over edge. Ease dough into plate by gently lifting edge of dough with your hand while pressing into plate bottom with your other hand. Leave any dough that overhangs plate in place. Wrap dough-lined pie plate loosely in plastic wrap and refrigerate until dough is firm, about 30 minutes.
4. Meanwhile, transfer 1 cup peach mixture to small bowl and mash with fork until coarse paste forms. Drain remaining peach mixture through colander set in large bowl. Transfer peach juice to liquid measuring cup (you should have about 1/2 cup liquid; if liquid measures more than 1/2 cup, discard remainder). Return peach pieces to bowl and toss with cornstarch. Transfer peach juice to 12-inch skillet, add pectin mixture, and whisk until combined.
Cook over medium heat, stirring occasionally, until slightly thickened and pectin is dissolved (liquid should become less cloudy), 3 to 5 minutes. Remove skillet from heat, add peach pieces and peach paste, and toss to combine.
5. Transfer peach mixture to dough-lined pie plate. Remove dough strips from freezer; if too stiff to be workable, let stand at room temperature until malleable and softened slightly but still very cold.
Lay 2 longest strips across center of pie perpendicular to each other. Using 4 shortest strips, lay 2 strips across pie parallel to 1 center strip and 2 strips parallel to other center strip, near edges of pie; you should have 6 strips in place.
Using remaining 4 strips, lay each one across pie parallel and equidistant from center and edge strips. If dough becomes too soft to work with, refrigerate pie and dough strips until dough firms up.
6. Trim overhang to 1/2 inch beyond lip of pie plate. Press edges of bottom crust and lattice strips together and fold under. Folded edge should be flush with edge of pie plate. Crimp dough evenly around edge of pie using your fingers. Using spray bottle, evenly mist lattice with water and sprinkle with remaining 1 tablespoon sugar.
7. Place pie on rimmed baking sheet and bake until crust is set and begins to brown, about 25 minutes. Rotate pie and reduce oven temperature to 375 degrees; continue to bake until crust is deep golden brown and filling is bubbly at center, 30 to 40 minutes longer. Let cool on wire rack for 3 hours before serving.
Pie dough for one nine-inch lattice top pie:
3 cups (15 ounces) all-purpose flour
1. Process flour, sugar, and salt in food processor until combined, about 5 seconds. Scatter shortening over top and process until mixture resembles coarse cornmeal, about 10 seconds. Scatter butter over top and pulse until mixture resembles coarse crumbs, about 10 pulses. Transfer to bowl.
2. Sprinkle 5 tablespoons ice water over flour mixture. With rubber spatula, use folding motion to evenly combine water and flour mixture. Sprinkle 5 tablespoons ice water over mixture and continue using folding motion to combine until small portion of dough holds together when squeezed in palm of your hand, adding up to 2 tablespoons remaining ice water if necessary. (Dough should feel quite moist.)
Turn out dough onto clean, dry counter and gently press together into cohesive ball. Divide dough into 2 even pieces and flatten each into 4-inch disk. Wrap disks tightly in plastic wrap and refrigerate for 1 hour or up to 2 days.
