5. Add 12 Tablespoons butter and process to blend (about 8 to 10 seconds), then pulse until mixture is a pale yellow color and resembles a coarse meal, (about three-1-second bursts).

7. Freeze butter and grate it on the large holes of a box grater into the flour mixture.
8. Toss butter pieces to coat.
9. Rub coated butter pieces between your fingers for a minute, until flour turns pale yellow and coarse.

11. Using both hands, firmly press mixture into an even, 1/4" layer over the entire pan bottom and about 1/2" up the sides.
12. Refrigerate for about 30 minutes.
