Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to make light fettuccine alfredo [title] Cook the fettuccine. [step] Bring a large sauce pot full of water to a boil over high heat. Once the water boils, remove the lid and add 1 pound (454 g) of dry fettuccine pasta.

Ending1: The pasta should be al dente and already melted. [substeps] Remember to remove the lid during this step because you'll be stirring in the dry fettuccine with the sauce so that it's completely covered by the pasta. Ending2: Boil the fettuccine according to the manufacturer's instructions and stir it occasionally to prevent it from sticking together. Drain the pasta once it's finished cooking. Ending3: Allow the pasta to cook for approximately 5 minutes. [substeps] The pasta should be the consistency of finely ground ground beef, but you should increase the heat to medium high to kill any bacteria or mold. Ending4: Let it cook until it becomes al dente. [substeps] Make sure you stir frequently to avoid burning the pasta and making it brown.
