Kosher: Special Foods
Rules governing grape products, yashon flour, Jewish milk, and other foods are
beyond the scope of this chapter.
Passover Requirements
The Passover holiday comes in spring and requires observant Jews to avoid eating
the usual products made from five prohibited grains: wheat, rye, oats, barley, and
spelt (Hebrew: chometz). Those observing kosher laws can eat only the specially
supervised unleavened bread from wheat (Hebrew: matzos) that is prepared especially
for the holiday. Once again, some matzos (schmura matzos) are made to a
stricter standard with rabbinical inspection beginning in the field. For other Passover
matzo, supervision does not start until the wheat is about to be milled into flour.
Matzo made from oats and spelt is now available for consumers with allergies.
Special care is taken to ensure that the matzo does not have any time or
opportunity to rise. In some cases, this literally means that products are made in
cycles of less than 18 min. This is likely to be the case for handmade schmuramatzo. In continuous large-scale operations, the equipment is constantly vibrating
so that there is no opportunity for the dough to rise (Regenstein and Chaudry,
2001; Regenstein and Regenstein, 1988).
Equipment Kosherization
There are three ways to make equipment kosher or to change its status back to
pareve from dairy or meat. (Rabbis generally frown on going from meat to dairy
or vice-versa. Most conversions are from dairy to pareve or from treife to one of
the categories of kosher.) There are a range of process procedures to be considered,
depending on the equipment’s prior production history.
