Charlotte and maybe Pat too (6)
I believe the answer is:
potato
'charlotte' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'maybe pat too' is the wordplay.
'maybe' indicates anagramming the letters.
'pat'+'too'='pattoo'
'pattoo' anagrammed gives 'POTATO'.
'and' is the link.
Can you help me to learn more?
(Other definitions for potato that I've seen before include "Food item (with eyes?)" , "The vegetable is just too pat" , "It's often baked" , "The staple food is strangely too apt" , "Common vegetable" .)
