Most of danger comes before fish dish (7)
I believe the answer is:
rissole
'dish' is the definition.
(rissole is a kind of dish)
'most of danger comes before fish' is the wordplay.
'most of' means to remove the last letter.
'danger' becomes 'risk' ('risk' can be a synonym of 'danger').
'comes before' means one lot of letters go next to another.
'fish' becomes 'sole' (I've seen this before**).
'risk' with its last letter taken off is 'ris'.
'ris'+'sole'='RISSOLE'
(Other definitions for rissole that I've seen before include "faggot" , "Losers I find in the chopped meat dish" , "Small cake of deep-fried minced meat" , "Fried ball of minced food" , "Fried meat/breadcrumb ball" .)
