Kneading can include salt water or not, but the water should be added gradually. The dough's hardness is up to your preference, but it's best if it's harder, as this makes the noodles smooth and chewy, and they are less likely to fall apart when cooked.NoodlesFor thinner noodles, cook until boiling once. For thicker ones, boil for an additional couple of times.(The term 'boil' here refers to the water coming out in a stream)

Remember not to cook them for five minutes; they will turn into a pot of soup if you do.

Actually, cooking is about gaining experience through practice. The more often you make it, the better you will get at it.I forgot to tell you that after kneading the dough, let it rest covered for a while, which is known as letting the dough rest.This gives the noodles more elasticity.
