Ron smells his mum's cooking, bacon, and the perfume he gave Hermione in OotP. Since there is no bacon tea, and even if there was, I'm not a fan of bacon in dessert or other weird places, I focused on Molly's cooking. I chose Blood Orange because she makes marmalade. I chose Dewy Cherry because she makes Christmas Cake. Christmas Cake in England is a fruitcake, so I went with cherries. The perfume part was hard because all it said was it smelled 'unusual.' I decided on pomegranate and rose hips because my friends and I thought her perfume would be sweet, woodsy, and/or floral.
