In a large bowl, combine the 00 flour, Granulated sugar, and Salt. Mix well.

Add the cold, cubed Unsalted butter to the dry ingredients. Using your fingertips, quickly rub the butter into the flour mixture until it resembles coarse crumbs. Avoid overworking the dough to keep it tender.

Add the Egg yolks and Lemon zest to the mixture. Gently bring the dough together until it forms a cohesive ball. Do not knead excessively.
