I remembered this last weekend as we were heading into the deep freeze. This was ridiculously delicious--thanks so much for posting it here.
I subbed pork for the chicken hearts and gizzards, and accidentally thought it called for ground chuck rather than chuck roast. I agree it could have used a teeny bit more ragu. I did make the pasta, but didn't realize the recipe also called for it to be hand rolled. I was thinking I could put the dough through my hand-cranked pasta machine, but it much too sticky for that. I did manage to roll it out, though instead of nice strips I had a bunch of weirdly shaped shards. But once everything was layered it was fine. I'll no doubt make this again next winter.
