Make the Pie Dough

• In a large bowl, combine the flour, salt, and sugar.
• Add Crisco and cut into the flour using a pastry cutter until the mixture resembles coarse crumbs.
• In a separate measuring cup, beat the egg with a fork. Add the vinegar, then fill with cold water up to the 1-cup mark. Stir to combine.
• Pour the egg mixture into the flour mixture and gently mix until the dough forms a soft ball. Use your hands if needed.
• Divide dough into 3 portions. Use 1/3 for the bottom crust, 1/3 for the lattice top, and reserve the final third for future pies (or discard if not needed).

Roll Out the Bottom Crust

• Roll one portion of the dough on a floured surface into a circle to fit your pie pan.
• Place the dough into the pan, allowing excess to hang over the sides.
• Gently press the dough into the corners and sides. Trim excess dough using scissors or a knife.

Prepare the Apple Filling

• In a large bowl, combine the sliced apples, granulated sugar, brown sugar, flour, cinnamon, and nutmeg. Mix thoroughly to coat all the apples.
• Pour the filling into the prepared pie crust.
• Dot the top with small pieces of unsalted butter.

Create the Lattice Top

• Roll out the second dough portion into a large circle. Cut it into strips 1/2 to 3/4 inch wide.
• Lay half the strips across the pie in one direction.
• Fold back every other strip halfway and lay one strip perpendicular to those.
• Unfold the folded strips, then fold the opposite strips and lay down the next perpendicular strip.
• Repeat until the lattice is complete.
• Trim the edges and crimp the top and bottom crusts together using your fingers or a fork.

Bake the Pie

• Preheat oven to 425°F (218°C).
• Place the pie in the center of the oven and bake for 15 minutes.
• Reduce temperature to 350°F (177°C).
• Open oven, check crust, and bake an additional 45 minutes.
• At 20 minutes into the second bake, brush the lattice crust with melted butter and sprinkle with sugar.
• At 30 minutes, tent the pie with foil if the crust is golden to prevent over-browning. (Create a foil tent by folding a sheet and creasing it to stand above the crust.)

Cool and Serve

• Remove the pie from the oven after 45 minutes total at 350°F.
• Cool on a wire rack for 3 hours to allow filling to set.
• Slice into generous 2-inch pieces and serve with ice cream or whipped cream.
