I haven't seen the film since it came out, so I can't remember the exact scene, however, nowadays we have microwave ovens and yet sometimes people choose to cook over an open fire (if you catch my drift).
Yes, it’s the scene where the kitchen staff are preparing turkeys. The young Vulcan officer then shoots the turkey in the pot as an experiment. I get the microwave idea yes. I just thought they have replicators in the Kirk time. I assume replicators came into use during Picards time?
FROM WIKI:
Apparently, the term "replicator" was not itself used until Star Trek: The Next Generation. In simple terms, it was described as a 24th century advancement from the 23rd century "food synthesizer" seen in Star Trek: The Original Series. In Star Trek the original series food was created in various colored cubes. In the animated series (1974), various types of realistic looking food could be requested as in the episode entitled "The Practical Joker". The mechanics of these devices were never clearly explained on that show. The subsequent prequel series, Star Trek: Enterprise, set in the 22nd century, featured a "protein resequencer" that could only "replicate certain foods," so an actual chef served on board who used "a hydroponic greenhouse" where fruits and vegetables were grown. Additionally, that ship had a "bio-matter resequencer" which was used to recycle waste product into usable material.
In the 23rd century, the United Federation of Planets had not yet perfected replicator technology for ships, though replicators already existed in industrial sites. Replicator technology was, however, in use by The Assigners, and the Beta 5 computer utilized replicator technology to manufacture several false identity cards for use by Gary Seven. (TOS: "Assignment: Earth") Starships of this time period were equipped with food synthesizers and other devices for producing clothing and machine parts on demand. This was a step forward, but did not achieve the quality and sophistication of the 24th century replicator. Replicator technology was not yet employed on starships as late as 2293. (TOS: "The Naked Time", "The Trouble with Tribbles"; VOY: "Flashback"; DIS: "Context Is for Kings", "The Butcher's Knife Cares Not for the Lamb's Cry", "Such Sweet Sorrow, Part 2")
Well in the original series, they utilized an inverse tachyon convection system to prepare most of their foods. While it wasn't instantaneous like the replicator, by folding space-time in a small, localized region and infusing the cooking apparatus with chronoton particles, time is slowed in the oven while the rest of the universe is on normal time. So due to the effects of time dilation, the food actually cooked for a normal duration in the oven, but to everyone around, it only seemed to take a minute. Now the Zakdornians from the Rigellian Space Coalition introduced many of the advances to Federation replicator technology between the original series and TNG.
There was that space station they came across, that was able to scan their databanks and upgrade the ship and provide them with all of the stuff they needed, and it had advanced replicator technology too.
If I remember correctly, the TNG Technical Manual said how it was blocks of biomatter, filled with complex molecules, that could be manipulated by the replicators, to make whatever was needed. I could be wrong, however.
