Rough Puff

Step 1
Place flour and salt in the bowl of a stand mixer fitted with a paddle attachment. Add butter and toss with your fingertips until evenly coated with flour.

Step 2
Add water to bowl. Mix on low speed until the dough forms a shaggy mass, about 45 seconds.

Step 3
Cover bowl with plastic wrap and refrigerate until butter is firm but not brittle, about 20 minutes.

Step 4
Transfer dough to a floured work surface and roll into a 1/2-inch-thick rectangle that is about 10 1/2 x 6 inches.

Step 5
Fold one third of the longer side of the dough over the center third of dough. Fold the final third over the center (like you would fold a letter). Tightly wrap folded dough in plastic wrap and refrigerate until chilled, about 30 minutes. Repeat this process of rolling, folding and refrigerating 4 more times, turning the dough 90 degrees each time before rolling.

Step 6
After completing the final fold, wrap the dough tightly in plastic wrap and refrigerate until firm, at least 1 hour or up to 2 days.
