"State the nature of your culinary emergency. Oh Gagh? You serve it FUCKING RAW, YOU DONUT!!"

It sounds like it would be a net-positive energy wise if they installed holographic emitters in the mess hall. Not only could they have one less person eating resources BUT they can greatly improve crew moral.

Then they can have a rotating roster of the best cooks, swapping between cultures or even cram all of that knowledge into a single hologram a'la the EMH.

While cooking is a complex chemistry exhibit that requires a lot of talent, it shouldn't take anywhere close to the amount of processing power an EMH does. It just doesn't need to know tens of thousands of procedures on dozens of alien species.

At most, it needs to know the equivalent of 'not to overly kneed biscuits' and 'it's a piece of cake to bake a pretty cake'

Speaking of holographic food, could you eat holographic food and have the same taste? Guessing you couldn't get nutrients from it but I am just imagining. Eating cake and pie and no calories.
