Fruitcake

Fruitcake was a food that originated on Earth.

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

He then 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)
