To make pasta, you firstly make a pile of your flour and form a well in the middle. Then you take your egg and fold in the flour until it forms a dough. Then you can use your hands to knead the dough until the eggs have gone into the dough. To check if your dough is the correct consistency, gently push down on the dough with one finger and the dough should raise back to its original position. Keep kneading the dough, not like bread dough. If some bits of the dough flake away from the dough then don't add them back in, just throw them out as they will break up the dough when you roll it out. Then you can either use a pasta machine or cut it with a knife to form your Pasta.
