Large serving spoon (5)
I believe the answer is:
ladle
'large serving spoon' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for ladle that I've seen before include "Large long-handled spoon" , "Soup or sauce server" , "Scoop" , "Serving implement" , "Spoon - a dell (anag)" .)
