NEW YORK (AP) — Like the indestructible Twinkie, Chicken McNuggets are practically a culinary punchline, a symbol of hyper-processed fast food with a list of ingredients that reads like a chemistry exam. While McDonald's did not give full details about what is or isn't in the test recipe, it said the new McNuggets do not have sodium phosphates, widely used food additives that the company has said can keep chicken moist. Last year, for instance, McDonald's changed its grilled chicken recipe to replace sodium phosphates with vegetable starch and to remove maltodextrin, which was used to increase browning.
