There are two major forms of matzah. Prior to the late 18th century, all matzah was soft and relatively thick, but thinner, crisper matzah later became popular in parts of Europe due to its longer shelf life. With the invention of the first matzah-making machine in France in 1839, cracker-like mass-produced matzah became the most common form in Europe and North America and is now ubiquitous in all
Ashkenazic and most
Sephardic communities.
Yemenite and
Iraqi Jews continue to use a form of soft matzah which looks like Greek
pita or like a
tortilla. Soft matzah is made only by hand, and generally with
shmurah flour.
Chocolate-covered matzah is a favorite among children, although some consider it "enriched matzah" and will not eat it during the Passover holiday. A quite different flat confection of chocolate and nuts that resembles matzah is sometimes called "chocolate matzah". Mass-produced matzah contains typically 111
calories per 1-ounce/28g (USDA Nutrient Database), about the same as
rye crispbread.
Shmurah matzah Shĕmura ("guarded") matzah (
matsa shĕmura) is made from grain that has been under special supervision from the time it was harvested to ensure that no
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. 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
Shulhan `Aruch record that it is the custom of some of Diaspora Jewry to be scrupulous in giving
Hallah from the dough used for baking "Matzat Mitzvah" (the shĕmurah matzah eaten during
Passover) to a
Kohen child to eat.
Egg matzah The requirement for eating Matzah at the Seder cannot be fulfilled with "[egg] matza." Many egg matzah boxes no longer include the message, "Ashkenazi custom is that egg matzah is only allowed for children, elderly and the infirm during Passover." Even amongst those who consider that enriched matzot may not be
eaten during Passover, it is permissible to
retain it in the home.
Chocolate-covered matzah Chocolate-covered matzah was sold in boxes as a standard product, alongside boxes of egg matzah. The matzah itself is not
Hamotzi (meaning that it is
Mezonot). == Cooking with matzah ==
