Sense correct as Tennyson shows (5)
I believe the answer is:
'sense' is the definition.
(taste is one of the five senses)
'correct as tennyson shows' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'TASTE' can be found hidden inside 'correct as tennyson'.
(Other definitions for taste that I've seen before include "Sample the flavour" , "Discrimination - a sense" , "Nice distinction felt in the mouth" , "Impression from food" , "Relish or discrimination" .)
