Passover

===Interpretations for abstinence from leaven or yeast===
Some scholars suggest that the command to abstain from leavened food or yeast suggests that sacrifices offered to God involve the offering of objects in "their least altered state", that would be nearest to the way in which they were initially made by God.<ref name="Bokser">Bokser, Baruch M.

There are also variations with restrictions on eating matzah before Passover so that there will be an increased appetite for it during Passover itself. Primarily among [[Chabad]] Chassidim, there is a custom of not eating [[Matzah|matzo]]h (flat unleavened bread) in the 30 days before Passover begins.<ref>{{cite web|url=https://www.chabad.org/library/article_cdo/aid/260800/jewish/The-Laws-Concerning-the-Thirty-Days-before-Passover.htm|title=The Laws Concerning the Thirty Days before Passover|website=www.chabad.org|access-date=April 1, 2020|archive-date=August 6, 2020|archive-url=https://web.archive.org/web/20200806062740/https://www.chabad.org/library/article_cdo/aid/260800/jewish/The-Laws-Concerning-the-Thirty-Days-before-Passover.htm|url-status=live}}</ref> Others have a custom to refrain from eating matzah from Rosh Chodesh Nissan, while the [[halacha]] merely restricts one from eating matzah on the day before Passover.<ref>{{cite web|url=https://www.jewishpress.com/judaism/halacha-hashkafa/eating-matzah-before-pesach/2012/03/29/|title=Eating Matzah Before Pesach|first=Rabbi J.

==== Kitniyot ====
[[Kitniyot]] ([[Hebrew language|Hebrew]]: קִטְנִיּוֹת, ''qitniyyot''; literally "small things") refers to legumes, rice, maize, and other foods that are similar to grains. [[Ashkenazi Jews]] historically refrain from eating kitniyot on Passover, despite there not being a clear commandment to include them in the category of chametz.<ref>{{Cite web |title=What is Kitniyot? |url=https://www.kashrut.com/Passover/Kitniyot/ |access-date=April 7, 2023 |website=www.kashrut.com}}</ref> Since the 19th century, the [[Reform Judaism|Reform movement]] has permitted eating kitniyot, and in 2015 the [[Conservative Judaism|Conservative movement]] followed suit.<ref>{{Cite web |last=Sanchez |first=Tatiana |date=April 21, 2016 |title=Passover to include new food options this year |url=https://www.sandiegouniontribune.com/lifestyle/people/sdut-passover-kitniyot-jews-2016apr21-story.html |access-date=April 7, 2023 |website=San Diego Union-Tribune |language=en-US}}</ref> [[Sephardic Jews|Sephardi Jews]] have always permitted eating kitniyot on Passover.

==== Gebrochts ====
Gebrochts ([[Yiddish language|Yiddish]]: געבראקטס, <small>[[Literal translation|lit.]] </small>'broken', also known as [[Hebrew language|Hebrew]]: מצה שרויה, <small>[[Romanization of Hebrew|romanized]]:</small> ''matzo shruya'', <small>[[Literal translation|lit.]] </small>'soaked matzo') refers to [[Matzah|matzo]] that has absorbed liquid. Some [[Hasidic Judaism|Hasidic Jews]] avoid gebrochts as well, to avoid the possibility that a clump of flour that was never properly mixed with water (and thus is still susceptible to leavening) may come into contact with the liquid.<ref>[http://www.oukosher.org/index.php/common/article/keeping_up_with_passover_trenditions/ Keeping Up with Passover Trenditions by Bayla Sheva Brenner] {{Webarchive|url=https://web.archive.org/web/20120330063056/http://www.oukosher.org/index.php/common/article/keeping_up_with_passover_trenditions/|date=March 30, 2012}} - ¶ 6: Hundreds of Passover Innovations – Oy Gebrocht!</ref>
