===Shmurah matzah===
{{main article|Matzah shmura}}
''Shĕmura'' ("guarded") matzah ({{langx|he|מַצָּה שְׁמוּרָה}} ''matsa shĕmura'') is made from grain that has been under special supervision from the time it was harvested to ensure that no [[Chametz#Fermentation|fermentation]] has occurred, and that it is suitable for eating on the first night of Passover. (''Shĕmura'' wheat may be formed into either handmade or machine-made matzah, while non-''shĕmura'' wheat is only used for machine-made matzah. It is possible to hand-bake matzah in ''shĕmura'' style from non-shmurah flour—this is a matter of style, it is not actually in any way ''shĕmura''—but such matzah has rarely been produced since the introduction of machine-made matzah.)

[[Haredi Judaism]] is scrupulous about the supervision of matzah and have the custom of baking their own or at least participating in some stage of the baking process. Rabbi [[Chaim Halberstam]] of [[Sanz]] ruled in the 19th century that machine-made matzah were [[chametz]].<ref>{{cite web|author=חיים בן אריה ליבוש האלברשטאם |url=http://hebrewbooks.org/pdfpager.aspx?req=913&st=&pgnum=77&hilite= |title=See SH"UT Divrei Hayyim Siman 23 |publisher=Hebrewbooks.org |access-date=2013-02-19}}</ref>  According to that opinion, handmade non-''shmurah'' matzah may be used on the eighth day of Passover outside of the Holy Land. However the non-Hasidic Haredi community of Jerusalem follows the custom that machine-made matzah may be used, with preference to the use of ''shĕmurah'' flour, in accordance with the ruling of Rabbi [[Yosef Chaim Sonnenfeld]], who ruled that machine-made matzah may be preferable to hand made in some cases. The commentators to the [[Shulchan Aruch|Shulhan `Aruch]] record that it is the custom of some of Diaspora Jewry to be scrupulous in giving [[Dough offering|Hallah]] from the dough used for baking "Matzat Mitzvah" (the shĕmurah matzah eaten during [[Passover]]) to a [[Kohen]] child to eat.<ref>[[Ba'er Hetev]] to [[Yoreh De'ah]] ch. 322 (minor par. 7), [[Shabbatai HaKohen]] to above chapter</ref>
