There is a set order for all that we do at the Seder.

There are also special Seder foods, each of which reminds us of some part of the Pesach story.

At the center of our table is the main Seder Plate, with the following:

Z'roa: a roasted bone. This reminds us of the special lamb which was offered on Pesach in the ancient Temple in Jerusalem.

Baytza: a roasted egg. In ancient times, on each of the three pilgrimage festivals (Pesach, Shavuot, and Sukkot) a sacrifice was offered in the Temple. The roasted egg reminds us of that Festival offering.

Maror: bitter herbs. Maror is a reminder of the bitterness and the hardship suffered by our people as slaves in Egypt. 

Charoset: This serves to remind us of the clay and mortar used by the Israelites when they made bricks for the pyramids and other buildings that they built for Pharaoh.

Karpas: a green vegetable. Karpas is a reminder of springtime, the season of Pesach when nature blooms again after winter and awakens our hope.
