Salt does not make water boil faster, in fact it raises the boiling point, so you have to provide more heat for the water to boil. But the water boils at a higher temp, so the pasta cooks slighlty faster.. Nor does salt keep pasta from sticking.. . The best method is to add about a Tbsp of salt to a large pot of water, before it boils. When the pasta is done, if you are not serving it immediately, toss it with a little olive oil to keep it from sticking.
