Does it taste like corn? (3)
I believe the answer is:
ham
'corn?' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ham that I've seen before include "Gammon" , "Pork leg" , "Thespian who overacts, informally" , "A poor actor - overdoes it" , "Bad actor; Noah son" .)
