Offering intended to appease or placate (3)
I believe the answer is:
sop
(Other definitions for sop that I've seen before include "Propitiatory offering" , "Concession given to mollify or placate" , "Piece of bread dipped in liquid, or a concession" , "Concession made to pacify troublesome person" , "Something of no great value given to appease" .)
