Questions tagged [kashrut-kosher]

Kashrut (also kashruth or kashrus, כשרות or כַּשְׁרוּת) is the set of Jewish dietary laws.

Kashrut (also kashruth or kashrus, כשרות or כַּשְׁרוּת) is the set of Jewish dietary laws. Food in accord with halakha (Jewish law) is termed kosher in English, from the Ashkenazi pronunciation of the Hebrew term kashér (כָּשֵׁר), meaning "fit" (in this context, fit for consumption by Jews according to traditional Jewish law). Food that is not in accordance with Jewish law is called treif (Yiddish: טרײף or treyf, derived from Hebrew טְרֵפָה trēfáh).
