Hugely how one enjoys one’s food? Not at first (14)

'hugely' is the definition.
Both the definition and answer are adverbs. Perhaps you can see a link between them that I don't see?

'one enjoys one's food? not at first' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'one's' could be 'as' (a thing is one thing) and 'as' is found in the answer.
'food?' could be 'a' (A is an example) and 'a' is located in the answer.
'not' could be 'no' (negative) and 'no' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'how' is the link.
