Tips for success: Don't skip the salting step - it's the key to non-soggy noodles. Use a hot skillet to evaporate any remaining moisture. Grate your own Parmesan for a smooth sauce. Cook the noodles just until heated through (about 2 minutes) or they will become limp. Store leftovers in the fridge for up to 1 day; reheat in a dry skillet over medium-high heat - not the microwave.
