Have you ever thought about why some foods make us feel happier than the others? (Humming the song , I-want-you-to-be-happier!!) The same mood-lifting effect when you cook or bake? 
Our body has a positive physiological and psychological response to some pleasant aromas. That’s the reason people stop to smell flowers. Another best example is lighting incense sticks at home, a common practice in India. When it comes to food, it’s not only the aroma that builds up the feel-good factor but the overall flavour which makes your experience delectable!
