I really don't know the answer to any of those questions. It doesn't make sense to me either.
My theory is that baking is like art therapy. A creative outlet. Only I'm not good at art, so I hate art therapy. HATE. But I AM good at baking.
So that's my best guess. Cooking as art therapy.
Anyway, I don't know the answer. But what I CAN say is this: To all the skeptics. To all the haters. To all the nay-sayers,
Don't even ACT like you don't want a cookie. :)
Or Truffles . . .
Etc . . .
