Vital woody plant juice I had found palatable (5)
I believe the answer is:
sapid
'palatable' is the definition.
(I've seen this in another clue)
'vital woody plant juice i had' is the wordplay.
I cannot quite understand how this works, but
'juice' could be 'sap' (juice from a plant) and 'sap' is present in the answer.
'i' is found in the answer.
'had' could be 'd' (in contractions e.g. 'I'd', 'you'd' etc) and 'd' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'found' is the link.
Can you help me to learn more?
(Other definitions for sapid that I've seen before include "Having a pleasant taste" , "savoury'" , "Pleasant tasting" , "Engaging" , "Tasty" .)
