This upcoming holiday season, the facts of traveling with food are more important than ever, as TSA agents never seem to have a solid grasp on what is and is not allowed in your carry-on luggage. Luckily for us, the TSA does have official positions on certain holiday foods, like cranberry sauce and pies. Hint: cranberry sauce is not allowed. Pies and cakes are allowed, but may be "subject to additional screening" (taste test?).
