Twisting in Bengali's net, unusual thing for eating (7)
I believe the answer is:
utensil
'thing for eating' is the definition.
(tool used when cooking or eating)
'twisting in bengali's net unusual' is the wordplay.
'twisting' says the letters should be written backwards (letters twist back).
'in' says the answer is hidden in the clue.
'lisnetu' can be found hidden inside 'bengalis net unusual'.
'lisnetu' reversed gives 'UTENSIL'.
(Other definitions for utensil that I've seen before include "E.g. colander" , "knife, maybe" , "Handy kitchen tool" , "Containers for kitchen use" , "A kitchen instrument or container" .)
