interesting topic, my ex-husband could make chicken kiev, chocolate souffle and some other fairly intricate dish when we married....he was 28 and had "special dishes" to impress women. Certainly incentive.
Growing up with a cooking family, my dad fished and loved to grill....he'd throw just about any protein in a green loaded out salad. It was not unusal for all of us (well except my little brother) to cook dinner together.
As adults my brother makes whole grain waffles that he grinds mixed grains then prepares with yogurt, eggs, baking soda....makes numerous as he has 5 children and freezes whatever is leftover for future breakfasts, normally he makes a monster batch at least once a week. He smokes and BBQ's, makes jerky from the deers he hunts.
My sons cook, they grew up cooking.....literally as soon as they could sit on a counter they were cooking....they were in the garden, they were at the store, they were eating out, they would choose themed parties....
finding a motivating factor, why would a guy choose to cook? What benefits would they derive? What aspects of cooking would interest them?
Most guys I know love butchering, smoking, BBQing.....
