My DF was so fussy, he hated getting his hands messy and was quite revolted at the thought of breaking an egg. He never cooked, having been brought up in a family with lots of women, including two older sisters. He was a stickler for clearing up, though, probably a hangover from his time on submarines in the war.
I'll never forget him coming into the kitchen when four of us were up to our elbows in the middle of preparing food for a party and declaring "this place needs a good clearup!".
He used to go sailing with a couple of other men and they seemed to manage in their tiny galley. He was spoilt by my DM's good cooking and always complained that they never got gravy on the boat. I think he managed to make some somehow to serve with the meal.
And, to his credit, they acquired a breadmaker quite late in life and he got great satisfaction weighing the flour, etc, and producing his own loaves.
