Really Flaky Pie Dough

Makes enough dough for one double-, or two single-crust pies.
2 1/2 cups (315 grams) flour
1 tablespoon (15 grams) sugar
1 teaspoon (5 grams) table salt
2 sticks (8 ounces, 225 grams tablespoons or 1 cup) unsalted butter, very cold
Gather your ingredients: Fill a one cup liquid measuring cup with water, and drop in a few ice cubes; set it aside. In a large bowl — I like to use a very wide one, so I can get my hands in — whisk together 2 1/2 cups flour, 1 tablespoon of sugar and a teaspoon of salt. Dice two sticks (8 ounces or 1 cup) of very cold unsalted butter into 1/2-inch pieces. Get out your pastry blender.
Make your mix: Sprinkle the butter cubes over the flour and begin working them in with the pastry blender, using it to scoop and redistribute the mixture as needed so all parts are worked evenly. When all of the butter pieces are the size of tiny peas — this won’t take long — stop. Yes, even if it looks uneven; you’ll thank me later.
Glue it together: Start by drizzling 1/2 cup (120 ml) of the ice-cold water (but not the cubes, if there are any left!) over the butter and flour mixture. Using a rubber or silicon spatula, gather the dough together. You’ll probably need an additional 1/4 cup (60 ml) of cold water to bring it together, but add it a tablespoon as a time. Once you’re pulling large clumps with the spatula, take it out and get your hands in there (see how that big bowl comes in handy?). Gather the disparate damp clumps together into one mound, kneading them gently together.
Pack it up: Divide the dough in half, and place each half on a large piece of plastic wrap. I like to use the sides to pull in the dough and shape it into a disk. Let the dough chill in the fridge for one hour, but preferably at least two, before rolling it out.
Do ahead: Dough will keep in the fridge for about a week, and in the freezer longer. If not using it that day, wrap it in additional layers of plastic wrap to protect it from fridge/freezer smells. To defrost your dough, move it to the fridge for one day before using it.
