A potto cooked and eaten (6)
I believe the answer is:
potato
'and eaten' is the definition.
I can't judge whether this definition defines the answer.
'a potto cooked' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'a'+'potto'='apotto'
'apotto' with letters rearranged gives 'POTATO'.
Can you help me to learn more?
(Other definitions for potato that I've seen before include "Would be difficult to deal with if hot" , "The humble spud" , "King Edward, for example" , "Plant tuber eaten as a vegetable" , "The veg is too apt, oddly" .)
