'seasoned' is the definition.
(salting is a kind of seasoning)
This is the entire clue.
(Other definitions for salted that I've seen before include "cured" , "Lasted, being preserved" , "Seasoned, given piquancy; (of meat) preserved" , "Like some nuts" .)
(Other definitions for weathered that I've seen before include "Worn by wind and rain" , "Strengthened by being exposed to the elements" .)
