For the love of all that is sacred, ALWAYS toss your pasta in its sauce before serving!
Cook your pasta to "al dente," remove from boiling water and throw directly into sauce. Keep sauce on simmer and toss your pasta, marrying the two heavenly ingredients. It will continue to slightly cook while soaking up all the delicious goodness. Key thing is to have your pasta taste like its a part of the dish instead of just "pasta WITH sauce."
