Fish a curious topping for ginger nut? (3,6)
I believe the answer is:
red mullet
'fish a curious topping' is the definition.
'red mullet' can be an answer for 'fish' (I've seen this before). I am not certain of the 'a curious topping' bit.
'ginger nut?' is the wordplay.
'ginger' becomes 'red ginger' (red hair).
'nut?' becomes 'mullet' (I am not sure about this - if you are sure you should believe this answer much more).
'red'+'mullet'='RED MULLET'
'for' is the link.
Can you help me to learn more?
(Other definitions for red mullet that I've seen before include "one's gathered in net" , "There's something fishy" , "Fish -- dull meter (anag)" , "Brightly coloured food fish" , "Tasty swimmer" .)
