Sweet line in fresh torte after drink (9)
I believe the answer is:
charlotte
'sweet' is the definition.
(type of pudding)
'line in fresh torte after drink' is the wordplay.
'line' becomes 'l' (used when specifying particular lines from a poem).
'in' means one lot of letters goes inside another.
'fresh' indicates an anagram (a fresh re-ordering of the letters).
'after' says to put letters next to each other.
'drink' becomes 'cha' (cha can mean tea).
'torte' with letters rearranged gives 'rotte'.
'l' going into 'rotte' is 'rlotte'.
'rlotte' put after 'cha' is 'CHARLOTTE'.
(Other definitions for charlotte that I've seen before include "Fruit dish" , "One of the Bronte sisters" , "Pudding; girl" , "Yorkshire novelist" , "sort of sweet" .)
