I'm a little stuck... Click here to teach me more about this clue!

'no longer interested in explorer's burn perhaps' is the definition.
I can't judge whether this defines the answer.

'no longer interested in explorer's' is the wordplay.
'no longer interested in' becomes 'over' (as in being over an ex).
'explorer' becomes 'Cook' (18th-century explorer Captain James Cook).
'over'+'cook'='OVERCOOK'

Can you help me to learn more?

(Other definitions for overcook that I've seen before include "Make a bad hash" , "Char" , "Do too much" .)
