This is, at the moment, Coco's favourite pasta sauce. She has always liked it, even when she was very young and I used to make it a little less hot. You can do the same, adapting it slightly to please your Coco. This is my original recipe revisited by Coco (less wine, more onion), who now makes the sauce totally by herself and serves it with penne, simply because penne are her favourite pasta shape. But bucatini (spaghetti-like tubes) are the traditional shape for Amatriciana and usually all children love them because they are fun to suck up.
