Southern dish for pepper (8)
I believe the answer is:
splatter
'for pepper' is the definition.
(thesaurus)
'southern dish' is the wordplay.
'southern' becomes 's' (abbreviation).
'dish' becomes 'platter' (platter is a kind of dish).
's'+'platter'='SPLATTER'
(Other definitions for splatter that I've seen before include "Spatter, splash" , "Sprinkle" , "Prattles (anag)" , "Make a mess" , "Small amount of something liquid" .)
