For this very reason, Passover Jewish matzo is unleavened, although some ritual liturgies insist it’s because fleeing Pharaoh on a moment’s notice didn’t allow Hebrews to wait for dough to rise. By this logic, cracker-like matzo memorializes escape to freedom. Changed circumstance is actually the theme of the ritual Passover meal: a Seder celebrates the shift from slavery (diners dip herbs into bitter saltwater that signifies tears) to independence (diners recline to feast on copious meat and vegetables). The Seder’s ritual of renewal, or resurrection, is perfectly choreographed to synchronize the soul with the arrival of spring. Now that we’re no longer caught in winter’s bleak grip, the Pascal (spring born) lamb bone, fresh parsley and whole cooked egg on the Passover table provoke our mind to embrace new opportunities.
