> If I describe the dish I want, and someone else makes it for me, I was still the catalyst for that dish. It would not have existed without me. So yes, I did "cook" it.

The person who actually cooked it cooked it. Being the "catalyst" doesn't make you the creator, nor does it mean you get to claim that you did the work.

Otherwise you could say you "cooked a meal" every time you went to MacDonald's.
