4. Myth: Put Oil in Pasta Water So it Doesn’t Stick.
Reality: Remember science class? Oil and water don’t mix! When you add oil to pasta water, it floats on the top — nowhere near the pasta it’s supposed to be preventing from sticking together. There’s really only one benefit to adding oil to pasta water: it will stop the water from boiling over if your pot is too short. If that’s not a problem, all you are doing is wasting expensive oil.
