I like this sauce with both long and short pasta. My mother always called it simply "Mostaccioli" when she made it and served it with short tubular paste that had lines on it and slanted ends. Just thinking of it makes me think of childhood!
Oh, my mother did manage to finagle the secret ingredient out of an old great aunt, who was probably going senile and didn't realize she was giving it away.
It was nutmeg.
I was there when she told some of her family, and laughed my culo off at the room full of Italians hitting themselves on the head with one hand. "It was nutmeg! NUTMEG!"
I stick with cinnamon, but someday I might try a pinch of nutmeg instead. :)
