Redhead produces something spicy (9)

I believe the answer is:

gingernut

I'm a little stuck... Click here to teach me more about this clue!

'something spicy' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'redhead produces' is the wordplay.
'redhead' becomes 'ginger' (I've seen this in another clue).
'produces' becomes 'nut' (I am not sure about this - if you are sure you should believe this answer much more).
'ginger'+'nut'='GINGERNUT'

Can you help me to learn more?

I've seen this clue in The Irish Times.
