The Seder plate

From Halachipedia

The Kaarah

  1. The Kaarah should be set with the three Matzot, Maror, Charotzet, Karpas, and two cooked dishes (in commemoration of the Pesach and Chagigah Korbanot) and the minhag is to use a roasted shank bone and an egg. [1]However, some have the practice of only using two Matzot. [2]
  2. Preferably the Kaarah should be set so that one doesn’t need to pass over one mitzvah to do another mitzvah and so one should put the Karpas is the highest/closest place because that’s the first mitzvah of the night. Afterwards, should be the Matzah, then the Maror, and finally the cooked dishes. However, some say it doesn’t matter where the cooked dishes or Maror are. [3]

  1. S”A and Rama 473:4 say that such is the minhag. The gemara in Pesachim 116a says that based on the pasuk of lechem oni, the matza should be broken and not whole, just like poor people's bread. Rif Pesachim 25b and Rambam Hilchot Chametz umatza 8:6 both rule that based on that there is no lechem mishna and we only have one whole and one broken. Tosafot Pesachim 116a "ma darko shel ani biprusa" says that we need to fulfill both lechem oni and lechem mishna so there is a requirement to have three matzas, two whole and the broken one. Shulchan Aruch 473:4 rules like tosafot. The Biur Hagra 473:4 rules like the Rambam because by having three you don't fulfill lechem oni.
  2. Haggadah of the Roshei Yeshivah (pg 14) records Rav Moshe's minhag to only use 2 matzot in accordance with the opinion of the Gra. See previous footnote.
  3. Rama 473:4 says that one should arrange the Kaarah so that one doesn’t pass over the mitzvoth. Mishna Brurah 473:36 says in name of the Chok Yacov that it doesn’t matter where the Karpas is because it’s not a mitzvah (as it’s only a zecher lemikdash). Mishna Brurah (Shaar Tzion 473:33) brings a machloket whether the Maror has to be placed in the order so as not to place over it.
