Dalek juice

In an alternative timeline,  was a flavourless, potable, black fluid secreted by a Dalek mutant as its flesh was boiled. When a captured Dalek was in the possession of Nigel Rochester, it was tortured frequently. One of the methods used, electrocution of a magnetic floor, would cause the mutant in the casing to boil and secrete a black fluid. The fluid was collected by guards and considered a rare delicacy. However, the amount collected was meager and it took months for the Dalek to recover sufficiently to be boiled again.

In 2003, the Sixth Doctor was given a small cup of this liquid to revive him after a fainting fit. He described the liquid as "rather tasteless". His companion, Evelyn Smythe, found the boiling and collection process obscene.

A marketing variation of this Dalek juice was known as "Dalek ade" or "Dalek squash". However, those drinks were merely ordinary lemonade or squash with an image of a Dalek on the bottle. (AUDIO: Jubilee)

In the primary timeline, during the Dalek invasion of Omnia, the Sixth Doctor removed a deceased Dalek mutant from its ruined casing to show to the Omnian resistance that the Daleks were mortal. Much to their disgust, the mutant, in addition to a rotting smell, leaked out a copious amount of Dalek juice. Agreeing, the Doctor quickly disposed of the mutant. (AUDIO: Emissary of the Daleks)
