“Flavor” is a complex word—although maybe not quite as multifaceted as “curry.” It seems so very simple to us when we use it to describe what we eat and drink, interchangeably with “taste.”
Wikipedia describes “flavor” as “the sensory impression of a food or other substance, determined by the three chemical senses of taste, olfaction (smell), and the so-called trigeminal senses (a merging of the ophthalmic, maxillary, and mandibular nerves), which detect chemical irritants in the mouth and throat.” You weed through all that scientific talk and end up at the old adage “You eat with all your senses.”
