Recover, having exploded in rage (6)
I believe the answer is:
regain
'recover' is the definition.
(I know that recover can be written as regain)
'exploded in rage' is the wordplay.
'exploded' indicates an anagram.
'in'+'rage'='inrage'
'inrage' is an anagram of 'REGAIN'.
'having' acts as a link.
(Other definitions for regain that I've seen before include "Possess once more for regina" , "Take back (the Ashes, for example)" , "Recover - in gear (anag)" , "Win back" , "Get back (previously owned object)" .)
