Food machine The food replicator or food machine was a device installed in TARDIS es which produced bars of food . They were engineered to replicate meals in flavour and nutrition . The Doctor ' s TARDIS possessed one . Features . The food machine had two large dials with selector needles on the front by which the codes for the various meals could be selected ( one dial bore numbers , the other letters ) , and dispensed foil - wrapped blocks , served on paper plates , that looked like blocks of cheese or tofu , but when eaten tasted like whatever food had been programmed into the machine – such as bacon and egg s . ( TV : " The Dead Planet " ) A food machine also stored water and milk , served in plastic sachets , which had to be replenished when empty because they weren ' t created by the machine . ( TV : " The Edge of Destruction " ) The food machine rearranged molecular deconstructed fungus into whatever delicacy was ordered . ( AUDIO : " Upstairs " ) Food machines came with a booklet which had codes for the food they could create . The code for eggs and bacon was J62 / L6 ( TV : " The Dead Planet " ) , while the code for spaghetti bolognese was KD / NB . ( PROSE : " Venusian Lullaby " ) The machines became obsolete , though , and were replaced by kitchens . ( HOMEVID : " Shada " , WC : " Shada " ) In the Doctor ' s TARDIS . The food machine was generally kept in the TARDIS kitchen , ( PROSE : " The Room With No Doors " ) though it was known to " wander " the corridors ( PROSE : " Christmas on a Rational Planet " ) . The Fourth Doctor once claimed that he had not seen the food machine in years . ( AUDIO : " The Fate of Krelos " ) The Seventh Doctor ' s companion Ace had the food machine near her room on the TARDIS . ( PROSE : " Echo " ) At some point , she made the food machine produce actual food instead of nutrient bars . The Doctor had intended to do the same , but never got around . ( PROSE : " Legacy " ) Uses . Vicki Pallister spent a long time programming the machine to produce a flavour like brown sauce after Ian Chesterton told her that Barbara Wright was fond of it . ( AUDIO : " 1963 " ) Steven Taylor once ate bacon and egg s from the food machine . ( AUDIO : " Upstairs " ) The Second Doctor got a hay - flavoured nutrient bar from the food machine and fed it to a sheep that had entered the TARDIS . ( PROSE : " Loop the Loup " ) At one point , the Second Doctor instructed Jamie McCrimmon and Victoria Waterfield on how to operate the food machine . ( AUDIO : " The Story of Extinction " ) When Jo Grant brought a Micro Servo Robot into the TARDIS , it connected itself to the computer and began transmitting adverts . One of these adverts had the food machine produce toast with written adverts on it . ( AUDIO : " Pop - Up " ) Chris Parsons discovered a food machine , which he thought was a minibar , in the guest suite aboard the TARDIS . He set the dials to K12 , but the food block he was served with tasted of steak and candy floss . ( PROSE : " Shada " ) After the TARDIS was stolen by Thomas Brewster , the food machine was one of the items which he removed from the TARDIS and sold to the crew of the " Gamma " who were marooned on the Time Reef . Although the Fifth Doctor was unable to recover the original food machine , he told Nyssa that he could easily build another . ( AUDIO : " Time Reef " ) The Fifth Doctor also used the machine to supply Erimem ' s cat Antranak with dead rat , much to his discomfort . ( AUDIO : " Nekromanteia " ) Frobisher found the food machine and nearly filled the console room with Mars Bar s . ( COMIC : " Voyager " ) Flip Jackson used the food machine to make popcorn . ( AUDIO : " The Fourth Wall " ) The Seventh Doctor asked and for a sample of their cooking so he could program it into the food machine . ( PROSE : " " ) The Eighth Doctor ' s companion Sam Jones tried to order French toast and orange juice from the food machine , though she thought it looked like a Mars Bar and carrot juice . ( PROSE : " War of the Daleks " ) Sam told the Doctor ' s other companion Fitz Kreiner that the TARDIS didn ' t have a kitchen , just a food machine . Fitz , who preferred making meals himself , found a kitchen , but wasn ' t sure whether Sam simply hadn ' t known about it , or if it had been created for him . ( PROSE : " Autumn Mist " ) While travelling with Alexander Pope and Theobald , the Ninth Doctor threatened to restrict their access to the food machine ' s viennetta . ( PROSE : " Double Falsehood " ) The Tenth Doctor tried to fix the machine , which had not been used in years . He failed and it produced food with disgusting flavours . He later used these food blocks to kill the Glutonoid . ( COMIC : " The Glutonoid Menace " ) By the time that the Tenth Doctor was travelling with Rose - the - cat , the food replicator was still in disrepair and had begun to sprout mould . The Doctor noted it while creating a list of places in the TARDIS which were in need of a cleaning , although Rose - the - cat did not recognise the machine . ( COMIC : " A Rose by Any Other Name " )
