Seafood found in cyclamen (4)
I believe the answer is:
clam
'seafood' is the definition.
(clam is a kind of seafood)
'in cyclamen' is the wordplay.
'in' says the answer is hidden in the clue.
'CLAM' can be found hidden inside 'cyclamen'.
'found' is the link.
(Other definitions for clam that I've seen before include "Shellfish - secretive type" , "What could grip" , "A silent type" , "Proverbially reticent marine mollusc" , "Mollusc with firmly-closed shell" .)
