Daughter ruined his recipe (4)
I believe the answer is:
dish
'recipe' is the definition.
'daughter ruined his' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'ruined' indicates anagramming the letters.
'his' is an anagram of 'ish'.
'd'+'ish'='DISH'
(Other definitions for dish that I've seen before include "Spoil" , "Particular item of prepared food" , "Kitchen container" , "someone very attractive" , "Shallow bowl" .)
