You remember the old ad campaign “Pork. The Other White Meat,” right?A lot of people do. For the pork industry, that’s a problem.The best-tasting pork chops, it turns out, aren’t the really pale, lean ones. They’re a darker pink color, marbled with fat.The famous ad campaign, launched in the low-fat ’80s by Omaha-born advertising firm Bozell, did almost too good of a job positioning pork as a lean meat, industry leaders now say.The fact that consumers still seek out whiter cuts — and then tend to overcook them into dry, white hockey pucks — contributes to falling sales of fresh pork among today’s flavor-seeking consumers. Of particular concern is consumer lack of interest in the pork chop. A slice of the pork loin, the pork chop ought to be a star, the way a steak is tops with beef.
