This is PIE CRUUUUUUST!
Okay, I’m a dork. Sorry! I couldn’t help myself.
Anyway. The recipe! This is courtesy of The Smitten Kitchen, and will make two pie crusts. I’m making a half batch in all the pictures I took.
2 1/2 c. flour
1 T sugar
1 t. salt
8 oz (2 sticks) unsalted butter
(We never have unsalted butter in the house, so I used regular and omitted the teaspoon of salt and it worked out fine)
Chill everything. Or at least the butter. Make sure it’s COLD. The refrigerator is your friend.
Cut the butter into cubes. I cut the stick of butter in quarters lengthwise, then cut those sticks into cubes. Dump everything into a really big mixing bowl. Significantly bigger than you’d think you’d need. Making pie crust is messy, and you don’t want to fling your flour all over your kitchen, or yourself. Like so:

See how that bowl looks way too big for such a small pile of ingredients? I was glad to have it. And I still ended up with flour on my pants.
Get one of these:

I guess you could cut the butter into your dough using two knives, but that sounds like an awful lot of work to me. This makes it much faster, and much easier.
Speaking of which: Cut the butter into your dough.
I used to be under the impression that the goal of cutting the butter in was to get a homogenous butter/flour mixture. Apparently, I was completely wrong. I have this irresistible urge to get Everything Completely And Thoroughly Combined, but I have to resist it when making pie, because apparently, you want chunks of butter. That’s what creates flakiness. D’oh!
This is good news, though, because it means you get to stop much sooner than you’re inclined to.
The general guideline I read is to cut the butter into your dough until it’s in “pea-sized chunks”. They really mean this. So when you’re cutting it in, stop every so often, squint at your butter chunks, and really ask yourself if peas are that size. Resist the inner voice that says, “No! Make them smaller!” Really look.
For reference’s sake, this is what my butter looked like when I decided it was done:

Look how chunky and uneven that is! It makes my poor baker’s heart weep with its lack of homogeneity. But it’s going to be delicious.
Now, get a glass of ice water and a spatula. Give the ice water a minute to really get chilled. Remember: cold. Cold cold cold.
Now dribble ice water onto your dough a little bit at a time, and mix it up with the spatula in between. You don’t want this to be too wet, or it’ll be sticky and unmanageable. Just add water until comes together and you don’t have any dry flour left in the bottom of the bowl. With this half batch, I dribbled water in two tablespoons at a time, and ended up putting in about 5 tablespoons of water total. It’ll look like this:

Now reach in there and mash it together. Just a little bit! I probably squeezed it four times total. You don’t want to work this much because that’ll form gluten, and gluten will make it chewy, not flaky. You definitely don’t want to knead it.
Form it into a ball, wrap it in plastic wrap, and flatten it into a disc. (If you’re making a full batch, divide it in half, and form it into two separate discs.)

See how it looks kina blotchy there? With darker-yellow spots in the middle of lighter-yellow bits? The darker yellow there is your chunks of butter. This makes my baker’s heart cry a little, too. But your taste buds will thank you. Just remind yourself that it’s good for it to be uneven.
Then stick it in the fridge and go read a book. Or write one, if you’re so inclined! It needs time to cool off after all that handling.
