Halakha, also transliterated as halacha, halakhah, and halocho, is the collective body of Jewish religious laws that are derived from the Written and Oral Torah. Halakha is based on biblical commandments (mitzvot), subsequent Talmudic and rabbinic laws, and the customs and traditions which were compiled in the many books such as the Shulchan Aruch. Halakha is often translated as "Jewish law", although a more literal translation might be "the way to behave" or "the way of walking". The word is derived from the root which means "to behave". Halakha not only guides religious practices and beliefs; it also guides numerous aspects of day-to-day life.
Kashrut is a set of dietary laws dealing with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. Food that may be consumed is deemed kosher, from the Ashkenazi pronunciation of the term that in Sephardi or Modern Hebrew is pronounced kashér, meaning "fit". Food that may not be consumed, however, is deemed treif, also spelled treyf. In case of objects the opposite of kosher is pasúl
Matzah, matzo, or maẓẓah is an unleavened flatbread that is part of Jewish cuisine and forms an integral element of the Passover festival, during which chametz is forbidden.
Shabbat or the Sabbath, also called Shabbos by Ashkenazim, is Judaism's day of rest on the seventh day of the week—i.e., Saturday. On this day, religious Jews remember the biblical stories describing the creation of the heaven and earth in six days and the redemption from slavery and the Exodus from Egypt, and look forward to a future Messianic Age. Since the Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the civil calendar is Friday.
The Mishnah Berurah is a work of halakha by Rabbi Yisrael Meir Kagan. It is a commentary on Orach Chayim, the first section of the Shulchan Aruch which deals with laws of prayer, synagogue, Shabbat and holidays, summarizing the opinions of the Acharonim on that work.
A hechsher or hekhsher is a rabbinical product certification, qualifying items that conform to the requirements of Jewish religious law.
A mashgiach or mashgicha is a Jew who supervises the kashrut status of a kosher establishment. Mashgichim may supervise any type of food service establishment, including slaughterhouses, food manufacturers, hotels, caterers, nursing homes, restaurants, butchers, groceries, or cooperatives. Mashgichim usually work as on-site supervisors and inspectors, representing a kosher certification agency or a local rabbi, who actually makes the policy decisions for what is or is not acceptably kosher. Sometimes certifying rabbis act as their own mashgichim; such is the case in many small communities.
Kosher wine is wine that is produced in accordance with halakha, and more specifically kashrut, such that Jews will be permitted to pronounce blessings over and drink it. This is an important issue, since wine is used in several Jewish ceremonies, especially those of Kiddush.
Challah or hallah, also known as berches in Central Europe, is a special bread in Jewish cuisine, usually braided and typically eaten on ceremonial occasions such as Shabbat and major Jewish holidays.
Kosher foods are foods that conform to the Jewish dietary regulations of kashrut. The laws of kashrut apply to food derived from living creatures and kosher foods are restricted to certain types of mammals, birds and fish meeting specific criteria; the flesh of any animals that do not meet these criteria is forbidden by the dietary laws. Furthermore, kosher mammals and birds must be slaughtered according to a process known as shechita and their blood may never be consumed and must be removed from the meat by a process of salting and soaking in water for the meat to be permissible for use. All plant-based products, including fruits, vegetables, grains, herbs and spices, are intrinsically kosher, although certain produce grown in the Land of Israel is subjected to other requirements, such as tithing, before it may be consumed.
Jewish cuisine refers to the worldwide cooking traditions of the Jewish people. During its evolution over the course of many centuries, it has been shaped by Jewish dietary laws (kashrut), Jewish festivals and holidays, and traditions centred around Shabbat. Jewish cuisine is influenced by the economics, agriculture, and culinary traditions of the many countries where Jewish communities have settled and varies widely throughout the entire world.
Negiah, literally "touch", is the concept in Jewish law (Halakha) that forbids or restricts sensual physical contact with a member of the opposite sex except for one's spouse, outside the niddah period, and certain close relatives to whom one is presumed not to have sexual attraction. A person who abides by this halakha is colloquially described as a shomer negiah.
In Judaism, the Ten Days of Repentance are the first ten days of the Hebrew month of Tishrei, beginning with the Jewish New Year Rosh Hashanah and ending with the conclusion of Yom Kippur. These days usually fall in September and/or early October.
Chametz are foods with leavening agents that are forbidden to Jews on the holiday of Passover.
Chalav Yisrael, also pronounced cholov Yisroel, refers to kosher milk whose milking was observed by an observant Jew. The halakha of chalav Yisrael, which originates in the Mishnah and Talmud, was instituted to ensure that no non-Jew would mix milk of a non-kosher animal with the kosher milk. Today, many kosher-keeping Jews rely on the ruling of Rav Moshe Feinstein, who argues that since countries such as the United States have strict laws against mixing milks, it can be assumed that the milk is kosher.
Bishul Yisrael is a Hebrew term for one of the laws of kashrut in Judaism. The rule prohibits eating certain foods if they are cooked exclusively by non-Jews. The term is the opposite of bishul akum, which the rule forbids. Akum (עכו"ם) is an acronym of Ovdey Kochavim U'Mazalot, literally "worshippers of stars and zodiac signs", but is actually a term for non-Jews).
In Judaism, a person who is shomer Shabbat or shomer Shabbos is a person who observes the mitzvot (commandments) associated with Judaism's Shabbat, or Sabbath, which begins at dusk on Friday and ends after sunset on Saturday.
Electricity on Shabbat refers to the various rules and opinions regarding the use of electrical devices by Jews who observe Shabbat. Various rabbinical authorities have pronounced on what is permitted and what is not, but there are many disagreements in detailed interpretation, both between different individual authorities and between branches of Judaism.
The mixture of meat and dairy is forbidden according to Jewish law. This dietary law, basic to kashrut, is based on two verses in the Book of Exodus, which forbid "boiling a (goat) kid in its mother's milk" and a third repetition of this prohibition in Deuteronomy.
Jewish law and custom prescribe ritual hand washing in a number of situations. This practice is generally known by the Hebrew term נטילת ידיים, which literally means taking up of the hands.
