I don't like to plug brand names here but sometimes they merit a mention -

"No more slimeburgers? Until recently, 70 percent of burgers in the United States contained “pink slime”, also known as ammoniated boneless lean beef trimmings, a cheap beef filling unfit for consumption until it is gassed with ammonia. Now McDonald’s, Taco Bell, and Burger King are dropping the magic additive following a campaign of withering criticism from celebrity chef Jamie Oliver."

I wonder what appetising ingredient will replace the missing bonne bouche.
