Fruit initially puréed with some corn (4)
I believe the answer is:
pear
'fruit' is the definition.
(I know that pear is a type of fruit)
'initially pureed with some corn' is the wordplay.
'initially' says to take the initial letters.
'with' means one lot of letters go next to another.
'some corn' becomes 'ear' (an ear is a piece of corn).
The initial letter of 'pureed' is 'p'.
'p'+'ear'='PEAR'
(Other definitions for pear that I've seen before include "Tasty fruit to reap" , "Variety of pome" , "Fruit; sounds like duo" , "Juicy fruit" , "Orchard fruit" .)
