Nut called Johnny gets us back (6)

I believe the answer is:

cashew

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

'nut' is the definition.
(cashew is a kind of nut)

'called johnny gets us back' is the wordplay.
'called johnny' becomes 'cash' (I've seen this in another clue. I am not sure about the 'called' bit.).
'gets' is a charade indicator (letters next to each other).
'us' becomes 'we'.
'back' is a reversal indicator.
'we' reversed gives 'ew'.
'cash'+'ew'='CASHEW'

Can you help me to learn more?
