Heavy, starchy food (6)
I believe the answer is:
stodge
'heavy starchy food' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stodge that I've seen before include "Dull work" , "Set dog (anag)" , "Sticky stuff" , "Steamed pudding" , "Heavy food (colloq.)" .)
