In a world of costly prime cuts—stately crown roasts, plump pork chops, and regal racks of lamb—it’s easy to forget about (and steer clear of) the more economical, but less lovable parts of the beast—bellies, brains, cheeks, combs, gizzards, hearts, hocks, kidneys, lungs, marrow, necks, shanks, spleens, tongues, trotters, and, oh yes, testicles. Historically, these so-called odd bits have had a regular place on our plates and in our culinary repertoires. In fact, many are considered delicacies and routinely appear in regional specialties. So why do we eschew and waste valuable protein? When have our sensibilities become so squeamish? In short—when did we decide offal had become awful?    Jennifer McLagan, award-winning author of Bones and Fat, is on a crusade to bring the nose-to-tail style of cooking and eating out of the closet and back onto to our dining tables.
