Perfect Piecrust

Martha Stewart's recipe for 2 crusts:

2 sticks unsalted butter, chilled, cut into small pieces, divided
2 1/2 cups all-purpose flour
1 teaspoon salt
1 teaspoon sugar
1/2 cup ice water

Lay out three-quarters of the butter pieces on a parchment-lined baking sheet and freeze for 30 minutes.  Refrigerate rest of butter.

Combine flour, salt, and sugar in a food processor.  Add refrigerated butter and pulse to combine 10 times.  Add frozen butter and pulse until mixture resembles course meal with some blueberry-size clumps.

With food processor off, add ice water all at once and immediately pulse until water is just incorporated- about 10 times.  Don't pulse so long that it forms a ball.  Squeeze a small amount of dough to see if it holds together.

Lay out two pieces of saran wrap.  Empty half the dough onto each piece.  Bring the edges of the dough together and press into disks.

Roll out disks, still wrapped in plastic, to 1/2 inch thick rounds 8 inches in diameter.  Refrigerate at least 45 minutes (and up to 2 days).  Can be frozen for 1 month.
