'completely overcooked' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'after a bad run contrite crook' is the wordplay.
'after' is a charade indicator (letters next to each other).
'crook' indicates anagramming the letters (a crooked or broken form of the letters).
'bad'+'run'='badrun'
'badrun' next to 'contrite' is 'badruncontrite'.
'badruncontrite' is an anagram of 'BURNT TO A CINDER'.

'is' acts as a link.
