Poet provides something for the gravy (8)

I believe the answer is:

browning

I'm a little stuck... Click here to teach me more about this clue!

'poet' is the definition.
(I know that Browning has the occupation poet)

I can't explain the rest of the clue.

(Other definitions for browning that I've seen before include "Play by Terence Rattigan" , "Toasting" , "English poet" , "Flour for colouring gravy" , "Gravy colouring; a poet" .)

I've seen this clue in The Guardian.
