Shulchan Orech
We begin the meal by eating the beitzah from the kaarah dipped in salt water, and continue with the rest of the Yom Tov meal. We eat the meal without leaning.
To prevent matzah from coming in contact with water (sheruyah), the matzos on the table should remain covered. Before pouring water (or any other liquid containing water) into a cup or bowl, check to ensure no matzah crumbs are inside. (This applies throughout Pesach as well, with the exception of Acharon Shel Pesach.)
Make sure to drink enough during the meal, so you won’t be thirsty after eating the afikoman.
Tzafun
Take two kezeisim from the afikoman (one to recall the korban pesach, and the second to recall the matzah eaten together with the korban pesach) and eat them while leaning to the left.
The shiur of the kezeisim for the afikoman (which is miderabanan) are ¾ oz. each. (If there are eight matzos to a pound, both kezeisim together equal ¾ of a matzah.) Each kezayis should be eaten within a kedei achilas pras.
If it is difficult for you to eat two kezeisim, you can eat one kezayis (i.e., 3/8 of a matzah) and stipulate that it recalls either the korban pesach or the matzah eaten together with it (whichever is the correct halachic opinion).
The afikoman should be eaten before chatzos. For the exact time in your location, visit www.chabad.org/zmanim.
Nothing should be consumed after the afikoman (except for the last two cups of wine), including water.
