Put flour and salt in a mixing bowl. Add eggs and yolks, and mix with hands or wooden spoon for a minute or so, until dough comes together. (Alternatively, use a stand mixer with a paddle attachment.) If dough seems dry or crumbly, add 1 or 2 tablespoons cold water, but only enough to keep the dough together.

Turn dough out onto a board and knead to form a ball. Flatten dough ball to a 1-inch-thick disk, wrap in plastic, and let rest at room temperature for at least 1 hour.
