Stew seasoning (5)
I believe the answer is:
thyme
'stew seasoning' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for thyme that I've seen before include "Strong herb" , "Herb with fragrant leaves - parsley, sage, rosemary and . . . . ." , "Minty herb" , "Plant used in cooking" , "Aromatic plant" .)
