The Seder table is different from our regular supper table. 

There are three pieces of Matzah in memory of the unleavened bread which the Jews ate when they were freed from Egypt.

Bitter Herbs for the bitterness of slavery.

The shank of a lamb as a reminder of the Paschal lamb.

A roasted egg symbolic of spring and new life.

Charoset, a food made of apples, nuts, cinnamon and wine, mixed together to look like the mortar which the Hebrew slaves used in their servitude.

Parsley, a symbol of spring is used as a token of gratitude to God for the products of the earth.

The salt water to dip the parsley in is a reminder of the tears our people shed during our slavery.
