Type of music — and French salad ingredient (6)
I believe the answer is:
rocket
'salad ingredient' is the definition.
(I've seen this before)
'type of music and french' is the wordplay.
'type of music' becomes 'rock' (I've seen this in another clue).
'and french' becomes 'et' ('and' in French).
'rock'+'et'='ROCKET'
(Other definitions for rocket that I've seen before include "that should take off?" , "Salad vegetable" , "Projectile salad ingredient" , "Salad leaves - move at great speed" , "In salad it's prepared" .)
