Traditionally, some Jews eat gefilte fish and matzah ball soup at the beginning of the meal. The piece of matzah set aside earlier is eaten as dessert, the last food of the meal. The children look for the Afikoman. Once it is found it is ransomed to the leader for a price as the Messiah was our ransom. The third cup of wine, called the redemption, cup is poured.
Grace is recited afterward.
Then a blessing is said over the third cup and it is drunk. The fourth cup is poured. The door is opened for awhile at this point for Elijah. Several psalms of praise are recited. A blessing is recited over the last cup of wine and it is drunk.
