A person or substance that adds flavor to food; one who creates or enhances flavors.
From 'flavor' plus the agent suffix '-er' (from Old English '-ere'), which creates nouns for people or things that perform an action. Common in words like 'teacher,' 'baker,' and 'singer'.
A 'flavourer' is a real profession in the food industry—flavor scientists create the compounds used in everything from candy to medicine, and they're sometimes called 'flavourists' in British English!
