Seaman Herbert Miller's arrival is highly anticipated as he is the first Navy classified cook to serve aboard the Reluctant, except he can't cook. Miller has been reassigned so many times Roberts allows him to stay, thinking he, Pulver and Doc can help him learn to cook. Captain Morton invites Admiral Morrison over for a meal. Roberts, Pulver and Doc cook it, giving Miller the credit who is immediately transferred by the Admiral to his flag ship. D'Angelo tells Roberts that Miller learned to be a signalman on his own so they send a recipe with cooking details to Miller on the flagship. Harry and George, the crew of a Japanese two man submarine, intercept the recipe and think they have stumbled on to a new code. Roberts spots the sub periscope, flashes a new recipe ""Sukiyaki Underwater"" and Miller informs Admiral Morrison who requests a patrol bomber.
