Adding cooking oil to pasta that is being boiled is widely believed to prevent the pasta from sticking. However, oil is an insoluble hydrophobic substance, such that it will float on the surface of the water. Therefore, the pasta (which sits on the bottom of the saucepan) has virtually no exposure to the oil during the cooking process. The oil may eventually come into contact with the pasta only after draining, although this is generally undesired, since it makes it much more difficult for any sauce to adhere to the pasta. The primary reason to add oil is to avoid foaming and/or boiling over.

I think Paul Ryan is also an insoluble homophobic substance.
