Food machine

The food machine was a device presented in TARDISes which produced bars of food, which had been engineered to replicate meals in the way of flavour and nutrition.

A food machine also stored water and milk which would need to be replenished when empty as these weren't created by the machine itself. (DW: The Edge of Destruction) Food machines came with a booklet which had codes for the types of food it was able of creating. (DW: The Daleks) The machine became obsolete later on and were replaced by kitchens that were much further away from the console room. (DW: Shada, WC: Shada)

The food machine dispensed foil-wrapped blocks that looked at first glance like blocks of cheese or tofu, but when eaten tasted like whatever food had been programmed into the machine. (DW: The Daleks)

Vicki Pallister spent a long time programming the machine to produce a flavour akin to brown sauce. (ST: 1963)

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. (ST: Pop-Up)

Ace was able to make the food machine produce actual food. (NA: Legacy)

Later, the Tenth Doctor attempted to fix the machine, which had not been used in years. He was unable to do so, giving food pills with disgusting mixes of flavours. He later used these food blocks to kill the Glutonoid, feeding him a fatal mixture. (DWBIT: The Glutonoid Menace)

The Seventh Doctor sometimes also made food in the conventional way. (NA: Cat's Cradle: Time's Crucible) The TARDIS also had a refrigerator that held milk and, presumably, other consumables. (IDW: The Whispering Gallery, DW: Shada, WC: Shada)
