Spaghetti is one of the easiest foods to prepare. Fill a pot with water, and wait for it to boil. Adding the noodles before the water boils will result in nasty soggy noodles, so always add them after. Boil time depends on the type of noodle, so be sure to stir and taste the noodles along the way. Also, it is vital that you add olive oil to the water just before putting the noodles in the water. If you do not do this, the noodles will stick together. Olive oil is especially pertinant when cooking lasagna noodles, so always remember to add it.
