Poets writing about sauce (5)
I believe the answer is:
pesto
'sauce' is the definition.
(pesto is a type of sauce)
'poets writing about' is the wordplay.
'writing about' indicates anagramming the letters (letters moved around or about).
'poets' anagrammed gives 'PESTO'.
(Other definitions for pesto that I've seen before include "Saucy work" , "Pasta sauce based on basil" , "Ligurian food" , "Sauce of basil, pine nuts, etc" , "Italian sauce containing basil" .)
