Reinserted fancy culinary implement (10)
I believe the answer is:
tenderiser
'culinary implement' is the definition.
'reinserted fancy' is the wordplay.
'fancy' is an anagram indicator.
'reinserted' is an anagram of 'TENDERISER'.
(Other definitions for tenderiser that I've seen before include "kitchen equipment" , "found in the kitchen" , "it's for improving the joint" , "Marinade, for example" , "tool?" .)
