how many here can recall scents when you're not smelling them? I can, but the spouse cannot--however, he's a hundred times better at identifying scents, as in, "there's a hint of rosemary in this". I find the ability to verbally identify scents magical.

Seconding the ability to verbally identify scents as a form of magic! Ditto tastes for me; I can describe what things taste like, often synaesthetically, but identifying ingredients in common parlance? Not so much. As for remembering how things smell... I think I can, but I'm not sure how reliable it is, if that makes sense.
