Pure recipe with new dried plum (5)
I believe the answer is:
Here is my best explanation:
'dried plum' is the definition.
(I've seen this before)
'pure recipe with new' is the subsidiary indication.
'recipe with' is an anagram indicator.
'new' becomes 'n'.
'pure' mixed up with 'n' gives 'prune'.
(Other definitions for prune that I've seen before include "Trim (tree); dried plum", "Dried plum", "Dull person", "A fruit; to cut back", "trim", "Trim - dried fruit", "Cut back the dried plum", "Shrivelled fruit" and "Dried fruit".)
