The Passover Seder is a ceremonial dinner held during the Jewish holiday of Passover, which commemorates the Exodus of the Israelites from slavery in Egypt. The Seder takes place on the first two nights of Passover and involves a specific order of rituals, readings, and symbolic foods. During the Seder, participants read from the Haggadah, a text that outlines the story of the Exodus and the significance of the holiday. Traditional foods served include matzah (unleavened bread), bitter herbs, and a sweet mixture called charoset, each representing different aspects of the Israelites' journey to freedom.
