Fruitcake

Fruitcake was a food that originated on Earth.

The Fourth Doctor told Jack Tyler to bring him four cups of tea and some fruitcake; he stated "I love fruitcake". He did this to create an everyday scene with which to bring Martha Tyler back into normality.

He proceeded to tell Martha how to make fruitcake, she told him that it wasn’t the right way to do it and was awoken from her trance. (DW: Image of the Fendahl)

Fitz Kreiner considered taking fruitcake with him every time he left the TARDIS as part of a packed lunch. (EDA: EarthWorld)
