In an attempt to influence cardinals and establish communication between the conclave and the outside world, messages have previously been hidden in food coming into the Sistine Chapel during the voting process.

Foods that could conceal messages such as pies and chickens, as well as cutlery and glasses, have been prohibited. Following tradition for the upcoming conclave, nuns will prepare local food such as lamb skewers, spaghetti, and boiled vegetables for cardinals.
