Refuse organic food? (5)
I believe the answer is:
offal
This clue could be a double definition.
'refuse' is the first definition.
(I've seen this in other clues)
'organic food?' is the second definition.
'offal' can be an answer for 'food?' (offal is a kind of food). I am not certain of the 'organic' bit.
Can you help me to learn more?
(Other definitions for offal that I've seen before include "Meaty waste" , "Edible animal viscera" , "Waste matter" , "cheap meat" , "Refuse - guts" .)
