Comparatively unbalanced means of presenting items for consumption (6)
I believe the answer is:
skewer
This clue is a double definition.
'comparatively unbalanced' is the first definition.
(skew can mean wonky or unbalanced)
'means of presenting items for consumption' is the second definition.
(food may be placed on a skewer)
(Other definitions for skewer that I've seen before include "Wooden or metal mat pin" , "Metal pin for cooking" , "Brochette" , "Small spit for meat" , "Meat-holding pin" .)
