Context paragraphs:
Challah: Challah ( , ; Hebrew: חַלָּה‎ ‎ "Halla" ] ), plural: challot or challos ) is a special Jewish bread, usually braided and typically eaten on ceremonial occasions such as Sabbath and major Jewish holidays (other than Passover).  Ritually-acceptable challah is made of dough from which a small portion has been set aside as an offering.  The recipe was borrowed by Ashkenazim from the traditional Eastern European braided breads known as kalach, kalács, kolach, or colac.

Kulich: Kulich (Russian: кули́ч ; ] , from Greek κόλλιξ - "kollix", and ultimately Hebrew: חלה‎ ‎ meaning a roll or loaf of bread) is a kind of Easter bread that is traditional in the Orthodox Christian faith and is eaten in countries like Russia, Belarus, Ukraine, Bulgaria, Romania, Georgia, Macedonia, Moldova and Serbia.

Challah cover: A challah cover is a special cloth used to cover the two braided loaves (challah) set out on the table at the beginning of a Shabbat or Yom Tov meal.  While its appearance lends a decorative and ceremonial aspect to the set table, its presence serves both a halakhic and symbolic function.

List of Arab salads: Arab cuisine salads usually accompany vegetable and meat dishes as well as breads will accompany any main course meal in the Arab world.

Hallulla: Hallulla (] , approximately like ; from the Hebrew "challah") is a popular bread in Chile.  The hallulla is a flat round bread baked with vegetable (but sometimes also animal) shortening and is used for several traditional Chilean sandwiches.  A typical white hallulla is similar in taste and texture to a scone, but is circular and larger, and more often used with savoury rather than sweet fillings.

Hallah (Talmud): Hallah (Hebrew: חלה, literally "Loaf"), although in the biblical sense that which refers to the "dough-offering," is the ninth tractate of "Seder Zeraim" ("Order of Seeds") of the "Mishnah" and of the "Talmud", treating on one of the twenty-four sacerdotal gifts mentioned in the Hebrew Bible.  During the period of the Jewish Temple, this "Hallah" was separated from bread made from either one of the five species of grain (wheat, barley, spelt, oats [var.  goatgrass] and wild barley [var.  rye]) and given unto a priest of Aaron's lineage (Kohen).  Today, since the priests are no longer ritually clean, the "dough-portion" is separated and burnt in the oven, or fed to birds in a few Jewish communities.  Before the Hallah is separated a blessing is said: "asher ḳiddeshanū bamitzvotau we'tzivanū le'hafrish challah."  The amount separated is only from bread products made from at least 1.2 kilos of flour or more (without a blessing) or 1.666 kilos or more (with a blessing according to some authorities) or 2.25 kilos or more (with a blessing) and is the size of a large olive.  If less than the requisite amount is used, some separate without a blessing while others do not separate at all.  If no separation is done while cooking, it can be done afterwards without a blessing.

Vánočka: Vánočka is a braided bread, baked in Czech Republic and Slovakia (in Slovak called "vianočka") traditionally at Christmas time.  It was first referenced during the 16th century, where it could only be made by a baker who was a guild craftsman.  During the 18th century, people took the recipe into their homes and began baking it themselves.  It is rich in eggs and butter, making it similar to brioche.  Lemon rind and rum add color and flavor; the dough can also contain raisins and almonds, and is braided like challah.  A "vánočka" may be built from three progressively smaller braids, stacked on top of each other; this is sometimes interpreted as a rough sculpture of the baby Jesus wrapped in cloth and lying in a manger.
