Tea

Tea was a drink made from the dried leaves of the tea plant, Camellia, created by brewing the leaves in hot water. Tea leaves were sometimes encased in porous bags, making it easier to dispose the leaves after steeping. (TV: The Invasion of Time, The Lodger, PROSE: The Dying Days) The Fifth Doctor once described tea to Will Chandler as "a noxious infusion of oriental leaves containing a high percentage of toxic acid". Will thought it sounded vile, to which the Doctor replied, "Personally, I rather like it". (TV: The Awakening) According to Samuel Johnson, the proper use of tea was to relax the studious, a claim the Fourth Doctor quoted while in the Morovanian Museum. (AUDIO: The Renaissance Man)

According to the Eighth Doctor, one should "never turn down tea if it's offered. It's impolite, and that's how wars start." Although at first claiming this to have incited at least fourteen different wars, he admitted that he may have been exaggerating when pressed. (AUDIO: Memory Lane)

When tea was not served with a meal, it was often served with biscuits and jam. (TV: The Power of Kroll) The Second Doctor once requested a patty cake with his tea. (TV: The Invasion) The Eleventh Doctor was particularly fond of Jammie Dodgers with his tea. He once fooled the Daleks into believing that the biscuit was the TARDIS self-destruct control.

(PROSE: Mrs Acres) Although unknown in England at least until 1420, (AUDIO: Oh No It Isn't!) tea later became prominent in British culture and was often drunk for comfort. When offered a cup of tea by her mother, Jackie in the middle of an alien invasion, Rose Tyler sarcastically referred to tea as "the solution to everything". Shortly afterwards, Mickey Smith dryly said to Rose that Jackie's offer of tea was the equivalent of "having a picnic while the world comes to an end" and "very British." (TV: The Christmas Invasion) Rose said to a parallel universe version of Jackie that her Jackie would not go to bed until she had a cup of tea, with two sugars. The parallel Jackie did the same as the one from Rose's universe. (TV: Rise of the Cybermen)

John's father had worked in the sugar fields in Jamaica, hence, the Doctor concluded, if he controlled people's taste buds so no one would take sugar with their tea, John's father wouldn't have had the job.
