I’m thinking of Cybertronian Cuisine again, because yes, cooking is a art and it reflects culture so I’m gonna world build the hell out of it
My first thought is that Vos would have a lot of dainty finger foods or pastries, like tea party fare
Cause that is what they would have, political tea parties. Hosting an event, even just having a friend over, would be taken seriously. A large variety of treats might reflect a host’s willingness to accommodate their guests but when entertaining fewer mechs it could mean a lack of familiarity with the invited. Having larger pieces of fuel could reflect poorly upon the host as it could be seen as an offensive way of “shutting up” the guest, therefore it has slowly become a trend amongst the upper class to serve increase more dainty and delicate morsels of fuel that remain bite sized to show off their wealth and status.
Lower caste Vosians wouldn’t steer towards intricate but would still favour small and compact as their flight frames consume fuel faster than grounders. Their goal is efficient and easy to eat fuel
Vos’ sister city Praxus would have similar inclinations, especially their pursuit frames, but they put less emphasis on fuel efficiency
This allows more enriched pastries to emerge, like Energon donuts (There’s probably a more clever name but I’ll cook on that)
Tarn as a major mining city would favour the pure state of filtered energon most as they have no time to invest in fancier processing of fuel for miners. They would have a lot of variations on classic liquid energon, lightly flavoured by various other common minerals found in their line of work
Nyon would be similar but they specialize in like family style fare, large pots of soups and stews meant to share. Their culture is huddling around their fuel and refueling together
Iacon as the bustling New York (or LA?) of Cubertron is where street food would be found. As it’s the cultural hub of Cybertron, cuisines all over the planet can be found here with various spins put on them to cater to a wider demographic.
Rust Sticks, a former byproduct of filtering raw energon was made popular in Iacon when a Tarnian realized with some added minerals the sticks could make it a sweet treat
Fried Silicon is a variation on the non-fried silicon gels of Vos, Vosian may call this creation a bastardized monstrosity of a respectable delicacy but Iaconian don’t really care, a servo sized glob of fried gooey goodness is all that matters.
Petrorabbit eggs are a delicacy in rural areas but a treat of the same name could be found in Iaconian stores made in imitation of the real thing with a silver casing and flavoured energon fillings
Anyways there’s probably more in my brain somewhere
I’ll expand on these later mayhaps
