Give last bits of rubbery scampi one final prod (5)
I believe the answer is:
yield
'give' is the definition.
(yielding is a kind of giving)
'last bits of rubbery scampi one final prod' is the wordplay.
'last bits of' indicates one should take the final letters.
The final letters of 'rubbery scampi one final prod' are 'YIELD'.
(Other definitions for yield that I've seen before include "Render" , "Chicken out" , "Succumb" , "Bring in -- give up" , "Produce as harvest or surrender" .)
