Oil in the Water: You may have heard that you can avoid sticky pasta by adding oil to the pasta water. This can prevent sticking, but at a great price. Pasta that’s cooked in oily water will become oily itself and, as a result, the sauce slides off, doesn’t get absorbed, and you have flavorless pasta.
Salted Water: Salted water flavors the pasta. A generous amount of salt in the water seasons the pasta internally as it absorbs liquid and swells. The pasta dish may even require less salt overall. For a more complex, interesting flavor, I add 1 to 2 tablespoons sea salt to a large pot of rapidly boiling water.
