Whisk together the flour, sugar, and salt in a large mixing bowl to evenly distribute the ingredients.
Add the cold, diced butter to the flour mixture. Cut the butter into the flour using a pastry cutter or fork until the mixture resembles coarse crumbs with pea-sized pieces.
Gradually add ice water, one tablespoon at a time, mixing gently with a fork until the dough holds together without being sticky.
Gently knead the dough a few times in the bowl, careful not to overwork it to keep butter pieces intact.
Divide the dough into two equal discs, wrap in plastic wrap, and refrigerate for at least one hour.
Remove one disc from the refrigerator and let it sit for a few minutes. Dust your work surface and rolling pin with flour, then roll out the dough to about 1/8-inch thickness.
Carefully transfer the rolled-out dough to your pie dish. Trim excess dough and crimp edges for a neat finish.
If pre-baking for cream pies, poke holes in the bottom with a fork to prevent bubbling, then bake as per your pie recipe.
