Pulp (5)
I believe the answer is:
puree
'pulp' is the definition.
(I have seen 'Smooth pulp ' mean 'puree' so perhaps 'pulp' could also mean 'puree')
This is the entire clue.
(Other definitions for puree that I've seen before include "Liquidise (vegetables etc)" , "Pulped vegetable or fruit" , "processed food?" , "Liquidised food" , "Smooth pulp of veg/fruit" .)
