That is so true, our senses of taste and smell are very closely linked so an unpleasant smell can really put us off eating something. The smelliest thing I probably cook with is garlic but I don't find that unpleasant.
I LOVE the smell of garlic! It smells so amazing when you heat it in olive oil. It tastes pretty darn good as well when sauteed in quality olive oil with fresh herbs and vegetables. I'm getting hungry just thinking about it, lol!
