Setter expecting parcels (6)

I believe the answer is:

pectin

'setter' is the definition.
(setting agent for jams etc.)

'expecting parcels' is the wordplay.
'parcels' says the answer is hidden in the clue (the answer is parcelled or packaged by the clue).
'PECTIN' is hidden within 'expecting'.

(Other definitions for pectin that I've seen before include "The gel in jam-making" , "Ingredient for setting jam" , "Setting agent in jams and jellies" , "Gelatinous substance in ripefruits, makes jam set" , "It thickens jam" .)

I've seen this clue in The Times.
