Trick may get huge flans recalled (9)
I believe the answer is:
stratagem
'trick' is the definition.
(thesaurus)
'get huge flans recalled' is the wordplay.
'get' means one lot of letters go next to another.
'huge' becomes 'mega' (I've seen this before).
'flans' becomes 'tarts' (I've seen this before).
'recalled' shows that the letters should be reversed in order.
'mega'+'tarts' is 'megatarts'.
'megatarts' in reverse letter order is 'STRATAGEM'.
'may' is the link.
(Other definitions for stratagem that I've seen before include "Plan to deceive enemy" , "Manoeuvre - Ma's target (anag)" , "Tactic to gain an advantage" , "Artifice" , "A cunning plan or scheme" .)
