Freedom fighter lends a lone man ingredients (6,7)

I believe the answer is:

nelson mandela

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

'freedom fighter' is the definition.
Both the answer and definition are singular nouns.
Maybe there's an association between them I don't understand?

'lends a lone man ingredients' is the wordplay.
'ingredients' is an anagram indicator.
'lends'+'a'+'lone'+'man'='lendsaloneman'
'lendsaloneman' anagrammed gives 'NELSON MANDELA'.

Can you help me to learn more?
