Tea

Tea was a drink made from the dried leaves of the tea plant, 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. (PROSE: The Dying Days, TV: The Lodger) 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)

Milk and sugar were often used to flavour tea. According to Professor Litefoot, ladies should add only one lump of sugar to their tea. (TV: The Talons of Weng-Chiang) Lemon was also often used to flavour tea. (PROSE: Fallen Gods)

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, both with and without his tea. He once fooled the Daleks into believing that the biscuit was the TARDIS self-destruct control. He claimed that he brought the biscuit since he was promised tea. (TV: Victory of the Daleks) Tea was prominent in British culture and often drank 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 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)
