technically, if you use that terminology, then the ROM should also be food because that's the final product.

from what I gather:

Kitchen = which basekit you are using (n2c 5054, Sprint 3.35 etc.) (recipe)

BuildOS = the actual app that builds your custom ROM (pots/pans/utensils)

OEM = programs that you "add" to the kitchen (think of them as seasonings)

ROM = final output of the kitchen you select, along with any OEMs you add. (your final product, a nice juicy steak or if you are a vegen, some veggie soup or garden burger)
