To serve: Bring a big pot of water to a rolling boil and add plenty of salt. Once the water is at a full boil, add the pasta, and stir immediately to prevent clumping (if you're using pasta that's been frozen, just add it directly to the pot; no need to thaw it first!). Let the pot come back to a boil. Cook, stirring occasionally. It will take only about 4 minutes to cook. The pasta is done when it is tender and floats to the surface. Drain it well and add the pasta to your favorite sauce.
