Fruit coated in flipping dry, old batter (9)

'old batter' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'fruit coated in flipping dry' is the wordplay.
'fruit' becomes 'olive' (I've seen this before).
'coated in' means one lot of letters goes inside another.
'flipping' says the letters should be written in reverse.
'dry' becomes 'arid' (similar in meaning).
'arid' back-to-front is 'dira'.
'olive' going inside 'dira' is 'DOLIVEIRA'.

Can you help me to learn more?
