I've refined the recipe over the years, improving my crust technique (I used to -- gasp -- use store-bought crust), and tweaking the filling. The basis of my filling recipe is my grandmother's famous pumpkin pie. One of the last years that my grandmother made pumpkin pie somebody was helping her, but they were flummoxed because she couldn't find the famous pumpkin pie recipe. It turned out it was on the back of the Libby's can of pumpkin.
The most recent iteration, which I record here for posterity, is a pair of hybrid recipes. The crust has the basis in a Cook's Illustrated recipe (but with all butter -- I'm morally opposed to shortening, and also we don't eat pork, so no lard), but with the clever rolling method from Alton Brown. The filling merges Libby's recipe (with a fresh pumpkin!) with an old New York Times recipe. Although you can substitute a can of pumpkin (not "pumpkin pie filling") if you wish.
Crust
Please follow the directions for the super-awesome pie crust here (but only make half the recipe, unless you're doing two pies. I won't judge you!)
You'll need to blind-bake the crust before filling.
Put oven rack on lower-middle position and preheat oven to 375 degrees Fahrenheit.
The next part really helps. Refrigerate dough-lined plate 30-40 minutes, and then freeze for about 20 minutes. The first refrigeration helps relax the gluten and minimizes shrinkage during baking; the second freezing improves the flakiness due to the different melting points of the flour and butter.
Put two layers of aluminum foil in crust and weight down with dry beans or pennies. Put in oven and bake until light in color, 25-30 minutes. Carefully remove the foil and bake for a further 5 minutes.
Makes 1 9-inch pie
1 pie-appropriate pumpkin
3/8 cup (3.5 ounce) white sugar
3/8 cup (3.5 ounce) packed light brown sugar
1 tsp ground cinnamon
1/2 tsp salt
1 tsp fresh grated ginger or 1/2 tsp ground ginger
1/8 tsp cloves
1/4 tsp nutmeg
2 eggs
5/8 cup whole milk
5/8 cup half-and-half
Preheat over to 350 degrees Fahrenheit. Take 1 medium sugar pie pumpkin or winter luxury pumpkin or french roasting pumpkin or (as I do) whatever they recommend at your favorite pumpkin-monger at the farmers' market. Cut in half lengthwise, and scoop out the seeds and stringy bits. This is a bit of a pain, and may require a paring knife as well as a spoon. However, getting out the stringy bits makes a much better pie! Line baking sheet with foil and place two halves of pumpkin pumpkin-side down. Bake for 1-1.5 hours until domes noticeably soften, but before things start getting very brown. Scoop out pumpkiny goodness from the shell into a bowl, and mash with a spoon. It may be fairly wet, so put the mashed pumpkin in a sieve to drain excess liquid. (I usually do this before I start the crust). (It is, of course, possible to skip this whole thing and use 1 can of pumpkin). Update: To effectively get the excess liquid out of the pumpkin, Christopher Kimball recommends lining a baking sheet with 3 sheets of paper towels, spreading the pumpkin, and then covering again with 3 more sheets. With some light pressing the paper towels will get saturated, and you end up with a nice sheet of perfectly textured pumpkinny goodness.
Preheat oven to 425 degrees Fahrenheit. Combine sugar, salt, cinnamon, ginger, cloves, and nutmeg in a small bowl and whisk to mix. Beat eggs in medium bowl. Add sugar mix and whisk together. Wait a few minutes and whisk again (to ensure that sugar dissolves completely). Whisk in mashed pumpkin. Update: If the mix is too lumpy at this point (when using fresh pumpkin) this mixture can be pulsed a few times in a food processor before continuing. Slowly add milk/half-and-half mixture and whisk to mix completely. Add filling and put in oven. After 15 minutes, reduce heat to 350 F. Bake for an additional 30-40 minutes until toothpick inserted in center comes out clean. Cool on wire rack.
