Put the bottom piece of matzah back on the tray, retaining the other two.
Recite:
Baruch atah Adonai, Eloheinu melech ha-olam, asher kid'shanu b'mitzvotav v'tzivanu al achilat matzah.
Praised are you, Adonai, Lord of the universe, who sanctified us with his commandment to eat matzah.
Each guest should break off a piece of the two matzah and eat.
