How does Firoozeh Dumas use imagery in Funny in Farsi: A Memoir of Growing Up Iranian in America?

Example of Imagery:

My Christmas kitchen smells of ginger, chocolate, and cinnamon. In my childhood kitchen, Nowruz smelled of cardamom, roasted pistachios and rose water. And in every Iranian living room, the sweet scent of hyacinths trumpeted the arrival of Nowruz and the beginning of spring.
