Of consuming interest (7)
I believe the answer is:
eatable
'of consuming interest' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for eatable that I've seen before include "Fit for food" , "OK to swallow" , "Fit for consumption" , "Edible" , "Digestible" .)
