Hendrix belief oddly not palatable (6)
I believe the answer is:
edible
'palatable' is the definition.
(associated in meaning)
'hendrix belief oddly not' is the wordplay.
'oddly not' means one should take alternating letters (not the letters in odd-numbered positions).
'hendrix'+'belief'='hendrixbelief'
The alternating letters of 'hendrixbelief' are 'EDIBLE'.
(Other definitions for edible that I've seen before include "Digestible" , "suited to diners" , "Esculent" , "Fit for consumption" , "in order to eat" .)
