Said to have a soft centre with pleasant taste (5)
I believe the answer is:
sapid
'taste' is the definition.
(I have seen 'excellent taste' mean 'sapid' so perhaps 'taste' could also mean 'sapid')
'said to have a soft' is the wordplay.
'to have' indicates putting letters inside.
'a soft' becomes 'p' (musical abbreviation for 'piano').
'said' going around 'p' is 'SAPID'.
'centre with pleasant' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for sapid that I've seen before include "Having a pleasant taste" , "Interesting" , "Engaging" , "savoury'" , "Tasty" .)
