Seder means Order or Arrangement ; and the arrangement of foods at the Seder reminds us of the many sided meaning of Passover, the great festival that marked the birth of free Jewish people thousands of years ago.
As on every Sabbath and Festival, candles grace the table. The blessing over the candles gives warmth to their light as they cast a holiday glow over the Seder, and those who have come to celebrate Passover.

The bitter herbs (usually horse radish) is a reminder of the bitterness of slavery.

For the children who snatch the Afikomen unseen , there will be a present for returning it upon request.
This roasted bone is a symbol of the Pesach Lamb sacrificed at the Ancient Temple.
