So many people like to add a drizzle of oil to the pasta water to keep them from sticking to each other. But the problem with this method is that because the pasta becomes slippery due to the oil, the sauce also has a hard time sticking to the pasta and doesn’t get absorbed properly. Next time you make pasta, try cooking it in a larger pot; this way it will release more starch, which means that it won’t all clump together.
