Adult pages left on record -- that is something fruity (5-3)
I believe the answer is:
'something fruity' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'adult pages left on record that is' is the wordplay.
'adult' becomes 'a' (abbreviation).
'pages' becomes 'pp'.
'left' becomes 'L' (common abbreviation).
'on record' becomes 'ep' (abbreviation for extended play record. I am not sure about the 'on' bit.).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
Can you help me to learn more?
(Other definitions for apple-pie that I've seen before include "Dessert - kind of bed or order" , "Perfect order -- bed jokily made" , "Sweet (in good order?)" , "Popular dessert" , "Common dessert" .)
