For all my dread of all things involving the kitchen, there is one thing I really enjoy about it ... the smell of freshly brewed coffee emanating from that room!
I have always loved the smell of freshly brewed coffee, even when I was a child and did not like coffee.
(The smell of stale coffee isn't offensive but just not nearly as pleasing.)
My second favorite kitchen aroma would have to be the smell of meat cooking in the crock pot with onions and seasonings.
I do so hate the smell given off by a sinkful of dishes that you keep putting off, and of course the odor in the fridge when something has evidently died in there. Yuck.
