? NOTES
Can I make it ahead?
Yes, you can make the whole thing ahead, then cool, cover and refrigerate for up to two days.
Reheat in a pan, on the hob, over a medium heat, stirring often. You'll probably need to add a few splashes of water or stock to loosen up the sauce.
Note: As the dish cools, the pasta will continue to absorb liquid, so the pasta will be a little softer upon reheating.
