Socialist with energy for every ingredient (9)

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

'socialist with energy for every' is the wordplay.
'socialist' becomes 'red' (socialism is often associated with the colour red).
'with' means one lot of letters go next to another.
'energy' becomes 'pep' (personal energy, vim).
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'red'+'pep'+'per'='REDPEPPER'
