The McRib sandwich is back, and with it, the horde of cult-like fans of the McDonald's pork sandwich.
Despite its name, the McRib sandwich actually contains no rib meat. But what exactly is it made of?
The Week explains some of the 70 ingredients of the McRib (which you may want to skip if you're a fan of the sandwich):
How many ingredients are there?
At face value, the sandwich contains just pork, onions, and pickle slices slathered in barbecue sauce and laid out on a bun. But the truth is, there are roughly 70 ingredients. The bun alone contains 34, says TIME's Melnick. In addition to chemicals like ammonium sulfate and polysorbate 80, the most egregious may be azodicarbonamide — "a flour-bleaching agent most commonly used in the manufactur[ing] of foamed plastics like gym mats the and soles of shoes." According to McDonald's own ingredient list, the bun also includes calcium sulfate and ethoxylated mono- and diglycerides, among other chemicals.
