Treat Crimea wounded outside gutted castle (3,5)
I believe the answer is:
ice cream
'treat' is the definition.
'crimea wounded outside gutted castle' is the wordplay.
'wounded' is an anagram indicator.
'outside' means one lot of letters goes inside another.
'gutted' means to remove the middle letters (to gut something is to remove its insides).
'castle' with its centre removed is 'ce'.
'crimea' is an anagram of 'icream'.
'icream' enclosing 'ce' is 'ICE-CREAM'.
(Other definitions for ice cream that I've seen before include "Party food" , "dessert will appear" , "Sweet frozen food" , "Hot day treat" , "Eric came to get confection" .)
