The tradition gave rise to the Russian word that expresses a person's hospitality: "khlebosolny" (literally: "bready-salty"). In general, the word "bread" is associated in Russian culture with hospitality, bread being the most respected food, whereas salt is associated with long friendship, as expressed in a Russian saying "to eat a pood of salt (together with someone)". Also historically the Russian Empire had a high salt tax that made salt a very expensive and prized commodity (see also the Moscow uprising of 1648).
