Myth: Salting Pasta Water Makes It Boil Faster.
Truth: Kind of, but not really. Adding salt to boiling water increases the boiling point of the water. Increasing the boiling point means that the water will reach a higher temperature and should cook the pasta better. However, to achieve this effect, you'd need to add 230 grams of salt to a liter of water, which would only raise the boiling point by 2 degrees Celsius and that is way more salt than anyone wants in their food! The good news is that adding salt to boiling water does flavor the water, which the food then absorbs. So, salting pasta water does enhance flavor, but not really the boiling process.
