Fresh dessert European covered in chopped mint (8)
I believe the answer is:
impudent
'fresh' is the definition.
(I know that fresh can be written as impudent)
'dessert european covered in chopped mint' is the wordplay.
'dessert' becomes 'pud' (short for pudding).
'european' becomes 'e' (abbreviation e.g. EU).
'covered in' indicates putting letters inside.
'chopped' is an anagram indicator (letters chopped or smashed up).
'pud'+'e'='pude'
'mint' is an anagram of 'imnt'.
'pude' put into 'imnt' is 'IMPUDENT'.
(Other definitions for impudent that I've seen before include "Lippy" , "Rude" , "Saucy" , "impolite" , "Audacious" .)
