Hagrid?

Come forth, investigate with your olfactory sensory neurons. Take a deep, slow inhalation from the characteristic spiral steam dancing from the cauldron, deep up your nasal passage. Let if consume your body as if it were the most desired drink. Before you cast your gaze onto the mother-of-pearl liquid, let your intense and short-lived passion infatuate you with your interpretation of the unique aroma. Of whom does it cause you to think?
