I recall egg, flour, and ????
Salt.
That's it - egg, flour and salt.
3 1/2 cups of flour, pile it on the counter and make a well in which you crack 4 eggs. Sprinkle with 2 pinches of salt, then start working the dough to combine.
You can get fancy and add basil or sundried tomato, maybe some olive paste, but the basic recipe is egg, flour and salt.
