For Jews, matzo is a baked product of considerable religious and ritual significance. Baked matzah bread can be ground up and used in other dishes, such as gefilte fish, and baked again. For Christians, bread has to be baked to be used as an essential component of the sacrament of the Eucharist. In the Eastern Christian tradition, baked bread in the form of birds is given to children to carry to the fields in a spring ceremony that celebrates the Forty Martyrs of Sebaste.
