Cook penne with cream for enduring quality (10)
I believe the answer is:
permanence
'enduring quality' is the definition.
(quality of enduring or remaining permanently)
'cook penne with cream' is the wordplay.
'cook' is an anagram indicator.
'with' means one lot of letters go next to another.
'penne' after 'cream' is 'creampenne'.
'creampenne' is an anagram of 'PERMANENCE'.
'for' acts as a link.
(Other definitions for permanence that I've seen before include "Indestructibility" , "Condition of being able to exist indefinitely" , "stability" , "Indefinite existence" , "Continuity, durability" .)
