Ingredients

2 sticks unsalted butter, chilled and cut into small pieces, divided 

2 1/2 cups all-purpose flour 

1 teaspoon salt 

1 teaspoon sugar 

1/2 cup ice water 

Preparation

Lay out three-quarters of the butter pieces on a parchment-lined baking sheet, and freeze until hard, at least 30 minutes. Refrigerate remaining butter.

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

Add ice water, and immediately pulse until water is just incorporated, about 10 times. Squeeze a small amount of dough to make sure it holds together. Pulse a few more times if needed.

Lay out 2 pieces of plastic wrap. Empty half the dough onto each piece. Bring edges of wrap together to gather dough. 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. Dough can be frozen up to 1 month.
