Boy with the French serving spoon (5)
I believe the answer is:
ladle
'serving spoon' is the definition.
(I've seen this in another clue)
'boy with the french' is the wordplay.
'boy' becomes 'lad' (informal term for boy).
'with' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'lad'+'le'='LADLE'
(Other definitions for ladle that I've seen before include "Soup-server" , "Soup or sauce server" , "Large spoon with long handle" , "Large long-handled spoon" , "Perhaps stock holder" .)
