What goes on a seder plate?
A seder plate (kearah) holds the symbolic foods of Pesach: zeroa, beitzah, maror, charoses, karpas, and chazeres, each part of retelling the Exodus.
What is the purpose of a seder plate?
It arranges the symbolic foods in a set order so they are ready during the Seder as we tell the story of Yetzias Mitzrayim.
What size seder plate do I need?
Choose one with room for all the simanim plus the three matzos nearby. A tiered or larger kearah suits a big Seder or hosting.
