Steve, I had to substitute for the pancetta, a mix of bacon and diced ham (and it had the smoke you cautioned about) and the bottle of stock I had in the freezer that was close to the correct amount was turkey stock (I have cubes, but preferred to use the real stock). And I ended up with more tomatoes (proportionately) than your recipe calls for, but I get the drift. I'll hunt for the non-smoked greasy pork to try it again later. This was okay, but I can see how it would be much better non-smokey, so I'll work on it. I made a half-size batch because I didn't have enough onion to make full sized. And that is a LOT OF ONION. Did you really mean a pound and a half?
