For a richer flavor, consider adding a pinch of nutmeg to the half-and-half while simmering.
If you prefer a lighter dish, you can substitute the half-and-half with heavy cream for a thicker sauce or whole milk for a lighter consistency.
This dish is best eaten fresh, as the pasta will continue to absorb the sauce and become soggy if stored for too long. If reheating, add a splash of milk or cream to restore creaminess.
