When I make noodles I never put any liquid in them. Just the egg and flour and sometimes salt sometimes not (depends on my mood) and they are pretty good (well havent had any complaints yet). I have tried them both ways yolks only and the whole egg. Now after reading this I should add some liquid to the yolk only ones as they are a real treat to mix. Was thinking of making a batch this week and now will try the liquid method just to see how they turn out.
