I believe the answer is:

apple core

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

'piece of fruit' is the definition.
I know nothing about this answer so I can't judge whether this works.

'peel mixed with copra' is the wordplay.
'mixed with' is an anagram indicator.
'peel' mixed up with 'copra' makes 'APPLE CORE'.

Can you help me to learn more?
