Essayist Francis (5)
I believe the answer is:
bacon
'essayist francis' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bacon that I've seen before include "Pork rashers" , "Meat in rashers" , "Cured pig-meat" , "Cured back or side of pork" , "Cured meat from pig" .)
