'cinnamon-tasting' originates from English, specifically the words 'cinnamon' and 'taste', where 'cinnamon' ultimately comes from Latin/Greek via Old French and 'taste' comes from Old French/Latin roots relating to tasting.

'cinnamon' comes into English via Old French (from Medieval Latin 'cinnamomum' and Greek 'kinnámōmon'), and 'taste' derives from Old French 'taster' (from Vulgar Latin *tastare, related to Latin 'gustare'); the compound 'cinnamon-tasting' is a modern English descriptive compound formed by joining these elements.

Initially the components referred to the spice ('cinnamon') and the act/quality of tasting ('taste'); combined as a compound adjective the phrase has the straightforward modern meaning 'having the taste of cinnamon'.
