seder

Order and ritual are very important in the seder—so important that they are even reflected in its name: the English word seder is a transliteration of a Hebrew word (sēdher) that means "order." The courses in the meal, as well as blessings, prayers, stories, and songs, are recorded in the Haggadah, a book that lays out the order of the Passover feast and recounts the story of the Exodus. Each food consumed as part of the seder recalls an aspect of the Exodus. For instance, matzo (unleavened bread) represents the haste with which the Israelites fled ancient Egypt; maror (a mix of bitter herbs) recalls the bitterness of life as a slave; and a mixture of fruits and nuts called haroseth (or haroset/haroses or charoseth/charoset/charoses) symbolizes the clay or mortar the Israelites worked with as slaves.
