Word for a curmudgeon (6)

I believe the answer is:

crusty

(Other definitions for crusty that I've seen before include "Well baked - short-tempered" , "Short" , "Curtsy (anag.)" , "Cross or harsh, like outer layer of loaf" , "Sour and brusque, like outer part of bread" .)

I've seen this clue in the Penny Press.
