Tzafun

1. Everyone should eat a k'zayit from the afikoman which was hidden away earlier in the Seder.
2. The afikoman should be eaten while leaning. After the fact, if one ate the afikoman without leaning and it is difficult to eat it again, one doesn’t have to eat it again.
3. The Mishnah Berurah writes that it is preferable to eat two kezaytim, one symbolizing the Korban Pesach and the other for the matzah eaten with the Korban Pesach.
4. One has until Chatzot to eat the matzah. If one didn’t eat any Matzah until Chatzot one should eat matzah after Chatzot without a Bracha of Al Achilat Matzah.
5. If one began late and there is a little time before Chatzot one should just say Kiddush, wash one’s hands, say HaMotzei and Al Achilat Matzah, eat the Matzah, and then make Al Achilat Maror and eat that before Chatzot and then complete the seder with the reading of the Haggadah and eating of the meal.
