Do you dread cooking pasta for the fear of it sticking together? Here is a tip to stop pasta from sticking when cooking. The trick is to treat the pot with nonstick spray before adding the water, or add a dash of oil or butter to the water. Also while boiling; if you place a spoon in a pot of pasta, it won't boil over. Whatever you do, never add the pasta before the water boils. If you do, you'll slow down the boiling process, and your pasta will stick together.
