Maybe her recipe for iced tea?

Now that federal investigators have Hillary Rodham Clinton’s homebrew email server, they could examine files on her machine that would be more revelatory than the emails themselves.
Clinton last week handed over to the FBI her private server, which she used to send, receive and store emails during her four years while secretary of state.The bureau is holding the machine in protective custody after the intelligence community’s inspector general raised concerns that classified information had traversed the system.
Questions about her use of the server have shadowed her campaign for the Democratic presidential nomination.Clinton again this weekend repeated a carefully constructed defense of her actions, in that she did not send or receive emails marked classified at the time.
