Seder Plates are used during the Passover Seder (Hebrew for order) and hold symbolic foods.
What's On A Seder Plate?
The traditional items on the Seder Plate are:
Maror — Bitter herbs, often horseradish, symbolizing the bitterness of slavery the Hebrews endured in Egypt
Chazeret -- A second bitter herb, often lettuce.
Charoset — A delicious mixture traditionally made from chopped nuts, grated apples, cinnamon, and sweet red wine, representing the mortar used by the Hebrew slaves to build the pyramids of Egypt
Karpas — A vegetable, often parsley, to be dipped into salt water
Z'roa — A roasted lamb shankbone symbolizing the Passover sacrifice, which was a lamb that was offered in the Temple in Jerusalem, then roasted and eaten as part of the meal on Seder night.
Beitzah — A roasted hard-boiled egg, symbolizes life and representing the korban chagigah (festival sacrifice) that was offered in the Temple in Jerusalem. Although both the Paschal Lamb and the chagigah were meat offerings, the chagigah is commemorated by an egg, a symbol of life and mourning because we are no longer able to offer sacrifices at the Temple in Jerusalem.
