The original recipe called for one half onion; I used a whole onion and liked it. I didn't really know what they meant by ¼ bunch thyme, so I used four three-inch pieces of fresh thyme. For ½ spring of rosemary, I used a two-inch piece of fresh rosemary. The original recipe also calls for oven braising, which can be done in a dutch oven, in a 325 degree oven, for about 5 hours (cook until the meat is falling off the bone). Finally, McNaughton uses his own, fresh-made "garganelli" pasta in this dish, but suggests penne as an alternative; I used casarecce, which is similar.
