Candy canes cooked in superior condition (10)
I believe the answer is:
ascendancy
'superior condition' is the definition.
'ascendancy' can be an answer for 'condition' (ascendancy is a kind of condition). I am unsure of the 'superior' bit.
'candy canes cooked' is the wordplay.
'cooked' indicates anagramming the letters.
'candy'+'canes'='candycanes'
'candycanes' is an anagram of 'ASCENDANCY'.
'in' is the link.
Can you help me to learn more?
(Other definitions for ascendancy that I've seen before include "Influential position" , "Condition of being dominant" , "Dominating influence (A, not E)" , "Candy canes (anag.)" , "Domination" .)
