It’s best to make this dough on a day that’s not too humid. You can make several batches on a cool day, wrap the disks in plastic and toss it in a zipper bag in the freezer. Pull them out about 1-½ hours before you want to make your pie and let them defrost a bit in the fridge. Roll them when they’re still nice & firm. They’ll keep well for about 3 months.
Use a food processor with a large-bowl (I use 12 qt – but if you don’t have one that big – just divide the recipe in 2) fitted with a steel blade.
Add to your bowl:
7 cups King Arthur flour - fluff your flour a bit before measuring it, so it’s not too compact
4 teaspoons of salt - I use kosher – it tastes better
Pulse a couple of times to mix
Then add:
5 sticks of very cold butter cut into bits. – Scatter around the bowl evenly
Pulse 5 or 6 times for about 2 seconds each pulse
If your butter gets too warm while you’re cutting it – toss in the freezer to harden up before putting it in the bowl
8 Tablespoons all-vegetable shortening bits – same as the butter - nice and cold
Pulse 5 or 6 times for about 2 seconds each pulse
At this point, your flour/fat mixture should still be grainy – It should look somewhat like coarse oatmeal. Don’t overwork the dough. Pulse only until the mixture just holds together when you squeeze it in your palm.
Turn your mixture out of the processor bowl and into another bowl –for some reason, glass bowls seem to work best.
Very slowly begin to add ice water. I evenly drop it around the perimeter of the bowl and gently lift and press the water into the dough with my fingertips only. For this amount of dough I have used up to 20 tablespoons of water and as little as 12 or 15 tablespoons when the weather is cranky and humid. You’ll have to get a ‘feel’ for it. Make notes for yourself each time you make it and recognize the changes so you’ll know what to do the next time. It’s scientific really – you need just enough water to make steam between the layers so that the fat & flour separate to make a fantastic flaky pie stratosphere!
Be the dough Alison.
When your dough is moist enough, wrap the bowl and put it in your fridge to ‘rest’. This gives the fats time to chill-out. If you don’t rest it, it can get mooshy when you’re rolling it. After about 30-40 minutes, take it out, cut into even sections and roll with a rolling pin – add flour to your work surface a little at a time as you go. Remember – the most important thing about making a great crust is not too much water and don’t overwork the dough. It takes a bit of patience –but your Dad will be psyched to see such a great piecrust!
