In a
food processor add flour, egg, egg yolks and salt. With processor on add 5 Tablespoons milk through the chute. The dough should come together easily and form into a ball. If it's too dry add an additional tablespoon of milk. If it's too dry add flour a tablespoon a time until dough forms easily into a ball. (You can also use a stand mixer or mix by hand. I just find the food processor to be the easiest for this.)
