Recalled trap set in identical puzzles (7)
I believe the answer is:
enigmas
'puzzles' is the definition.
(I've seen this before)
'recalled trap set in identical' is the wordplay.
'recalled' says the letters should be written backwards.
'trap' becomes 'gin' (gin trap is a kind of animal trap).
'set in' is an insertion indicator.
'identical' becomes 'same' (similar in meaning).
'gin' put within 'same' is 'samgine'.
'samgine' backwards is 'ENIGMAS'.
(Other definitions for enigmas that I've seen before include "They're mysterious or difficult to understand" , "'Mysteries, riddles (7)'" , "Puzzles - mysteries" , "'Puzzles, riddles (7)'" , "Problems" .)
