Step 1 In a food processor, pulse the flour and the salt to mix. Add the whole eggs and 1 egg yolk and process until the dough begins to come together in a large ball, about 2 minutes. If the dough only gets sandy, it is too dry and you will need to add the extra egg yolk.
Step 2 Gather the dough into a ball and knead it on a lightly floured surface just until smooth, 4 or 5 strokes. Wrap tightly with plastic wrap and set aside for at least 30 minutes to rest.
