I made a couple of these today:
But to explain how and why, I must tell you about Dewey and his brother, who are a pair of bachelors who live at the end of the road (an increasingly unrepaired dirt road that gets less and less like a road as you go along) up the local mountain. Almost all their lives they have had no running water and no electricity, although maybe they now have electricity - it's been a couple of years since I last was up there. Probably the happiest and most contented people I know, they seem to come to town (Ahem! 600 souls is certainly a town!) once a week or so by hitching a ride from neighbours they must walk down to. You know when they are coming, much as with a bear or a skunk, and that's all I need say about that. Lovely, kind, generous guys. Each summer, Dewey goes across his lane to the enormous blueberry fields (not his, as he openly admits) and spends a few minutes raking and brings me the results. So I make two pies, or this year, two tarts. One for me, and one for him. One of these days I should go and claim back the nice non-stick pie dishes that he has acquired from me over the years; I've only one left. So these were made in disposable tin trays.
Crust is my standard short crust pastry, with a tablespoon of sugar added since it's not a savoury pie we're making.
1⅓ cups white flour
¼ tsp salt
1 TBSP sugar
4oz shortening (I use Parkay brand veg. shortening, because of SWMBO), COLD, cut into tiny cubes
Place all in a food processor and pulse until the resulting crumb is like breadcrumbs. Maybe 30 seconds in all. Open the lid and start to add ice cold water I TBSP at a time while you pulse. Somewhere between 4 and 6 TBSP the pastry will form into a ball and then you stop. Whether it's 4 or 6 depends on the brand of shortening: Parkay is 4, and Imperial is 6, depends on the water content in the grease. Either way, you add until it goes into a ball. Scoop out your pastry, divide into two equal halves, and wrap each in clingwrap and place in the fridge for a minimum of 30 minutes. Wash the food processor and grease a couple of pie dishes. The paper wrapper the shortening came in will do for this.
After 30 minutes or longer, take out the pastry and roll out on a floured surface until it has a diameter of 9-10" (pie dishes are usually 9" diameter). Place pastry on dish, press down into the base, and trim off excess. Prick the pastry in the bottom with a fork in five or six places, as this lets out steam and stops the pastry rising off the bottom. Now we blind bake them, that is to say, we cook the pastry and the filling separately, unlike the way your mom made apple pie.
Cover each dish with aluminum foil, shiny side down, folding the edge down around the edge of the dish and pastry. We have to weight down the foil, and I have a large canister of old pennies for this, but you could use rice or beans. Just keep them for repeat use in the future, as you won't want to make chili with them after they have been baked. My oven will bake these pie crusts at 350ºF in 30 minutes, but you may need to take one out and look under the foil at 20, 25 minutes; ovens are all different. When done, let them cool a bit and then carefully separate the foil and its load of old coins/beans or rice. Leave the crusts to cool down while you make the filling.
Filling is 3 cups of blueberries per crust, 2 TBSP cornflour (or cornstarch depending on where you live) per crust, ¼ cup sugar per crust and 1 tsp lemon juice per crust. So I put twice of all those in a pan since I have just made two piecrusts. Shake or stir it a bit to coat the blueberries in the cornflour and sugar. Put it on medium heat, put a lid on it, and stir gently every few minutes. Once it simmers, the filling will thicken and be ready in 5-8 minutes. Pour into the pie crusts when it has cooled a little, then leave them to cool completely.
I've wrapped one in a plastic bag and put it in the freezer for the next time Dewey comes to town. The other will be served tonight after a curry. It will go nicely with cream, ice cream, or custard.
