...not that we don't have feral pigs with a little wild boar in the historical breeding mix here in Northern California. When I lived in Clayton for a little while (in Contra Costa County), I would read news reports of the wild/feral pigs that are the scourge of parks in and around Mt. Diablo, but no... we used pork shoulder.
One thing that struck both of us about the recipe is that it seemed like it hadn't been adapted for pork instead of wild boar. Some of the aromatics (juniper berries, cloves) and methods (boiling the meat before searing and braising it - don't do it) seemed more oriented towards game so we made some changes that I'll pass along in the recipe. In addition to the stew and polenta - we went a different direction with the polenta - we had roasted asparagus (Spring!) with garlic, salad and we drank a San Giovese with dinner.
