Mixture of foods daughter sadly brought up (5)
I believe the answer is:
salad
'mixture of foods' is the definition.
(a salad is a mixture or combination of foods)
'daughter sadly brought up' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'sadly' becomes 'alas' ('alas' is used to express regret).
'brought up' shows that the letters should be reversed in order (in a down clue, letters go up).
'd'+'alas'='dalas'
'dalas' in reverse letter order is 'SALAD'.
(Other definitions for salad that I've seen before include "healthy food" , "See 1 ac" , "vegetarian dish" , "Cold dish of vegetables or fruits" , "One that may be dressed for dinner" .)
