This was Todd's contribution - we'd sort of burned out on pork and beans, and hadn't really tried making anything with a Mexican slant lately. We poured through our Rick Bayless and Diana Kennedy cookbooks, and eventually turned back online where Todd discovered this great al pastor recipe.
He marinated it as directed, but instead of cooking it in a pot, he cooked it in the crock pot the next day. Initially we weren't thrilled with the results, but after making some homemade masa cakes and frying the pork in the skillet, it took on much better results!
