In a large bowl, whisk together flour, salt, and sugar.
1⅔ cups all-purpose flour, ½ tsp salt, ½ Tbsp granulated sugar
Add chilled butter cubes. Working quickly, flatten each piece between your fingers until the mixture looks like coarse crumbs with some pea-sized butter pieces. Work fast to keep butter cold, this creates flakiness.
12 Tbsp unsalted butter
Add 4 Tbsp ice water and toss with your hands. Add more water 1 Tbsp at a time until dough just barely holds together when squeezed (usually 5-6 Tbsp total). It should look shaggy, not smooth.
5-7 Tbsp ice cold water
Press dough into a flat disc, wrap tightly in plastic wrap, and refrigerate for at least 1 hour.
Laminate for Extra Flakiness (Optional but Worth It!)
After chilling, roll dough into a rough 10×6-inch rectangle on a floured surface.
Fold in half like a book, then fold in half again (you've folded it in quarters). Roll out and repeat once more. This creates those beautiful flaky layers.
