Storage: First cool any leftover pasta to room temperature, then transfer it to an airtight container and place in the refrigerator. It will last about four days in the refrigerator. To reheat, microwave on high in 30-second increments until warmed through. You can also reheat it on the stovetop. Place the pasta in a medium saucepan over low heat along with a splash of milk or water and heat gently, stirring occasionally, until warmed through.
