My mother makes creamed onions once a year. Every year, on Thanksgiving, she boils a big pot of little pearls, burns her fingers slipping them from their skins, and coats them with a glorious sauce of cream, flour, pepper, and salt. It takes forever, and by the time she finishes, she needs a good 365 days of rest before she's able to work up the zeal to do it again.
It's how I feel about Concord grape pie.

All that is beyond actually adding the other ingredients for the filling, not to mention making the pie crust and all the work that goes into rolling it out. It takes a solid hour and a half of hands on time, with a five hour wait in between. You can understand why it's hard to muster up the excitement more than once every 365 days.
But the thing is, on that one day, it's so worth it. The stained fingers and floured counter and grape seeds dotting the sink are nothing compared to the taste of this pie. If you can imagine the best of a Concord grape—all of the sweetness and flavor and intensity it holds—if you can imagine all that exceptionalism, imagine cooking it down. Imagine concentrating that flavor into an even sweeter, even more intense, even more exceptional filling, and then wrapping it with buttery, flaky pie crust. It is sheer delight.

CONCORD GRAPE PIE
Adapted from a recipe by Irene Bouchard of Naples, New York published in the Naples Record, Volume 134, Number 27, on Wednesday, June 30, 2004.
Grape pie isn't one of the fruit pies most of us grow up with. It might sound like a strange idea, but I promise you, it's worth a try. What isn't worth it is substituting red or green seedless grapes from the grocery store—they offer nothing near the flavor of a Concord, and they don't have the right texture, either.
dough for one 9-inch pie crust, top and bottom
5 and 1/2 cups Concord grapes
1 cup sugar
1 tablespoon tapioca
Remove the skins from the grapes by pinching them over a bowl. Collect the pulp in that bowl, and save the skins in another. Put the pulp into a saucepan (you do not need to add any water) and bring it to a rolling boil. Turn down the heat and let it simmer for five minutes. Crank the hot pulp through a food mill or rub it through a strainer to remove the seeds. Mix the hot, strained pulp with the skins, and let the two stand together for five hours. (This gives the filling a deep purple color.)
Preheat the oven to 400 degrees F. Roll out half of the pie crust and drape it across the bottom of a 9-inch pie plate. Add the sugar and tapioca to the grapes, stir well, and pour into the plate. Roll out the remaining pie crust so that it is big enough to center the pie plate on top of it. Use a small knife to cut a "floating" top crust, tracing a circle roughly 1/2-inch bigger than the base of the pie plate. Place this crust on top of the filling and cut a design in the top to allow steam to escape. (The floating crust gives the pie a very pretty look, making a purple ring around the outside, and also helps prevent disaster as the grape filling tends to boil over. I like to cut a small hole in the center and rays coming out for an even prettier effect.)
Bake the pie for 20 minutes. Turn the oven down to 350 and bake for 20 minutes longer, or until the crust is golden brown and the filling is set. Let the pie cool for one hour before serving.
