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

'food item' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'elevate film shot at acapulco finally' is the wordplay.
'elevate' becomes 'jack' (jacking is a kind of elevating).
'film shot' becomes 'etpot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'finally' suggests the final letters.
The last letter of 'acapulco' is 'o'.
'jack'+'etpot'+'at'+'o'='JACKET POTATO'

'to' acts as a link.
