Jews from Spain, Italy, Sicily, Morocco, Tunisia, and Sardinia would bring the Seder plate to the table with ceremony. Sometimes, they would cover it with a nice scarf and sing as it arrived to the table. They would pass it from person to person around the table, and place it on each head for a moment. This demonstrates that we were once slaves in Egypt and carried heavy burdens on our heads. In Hungary, they go even further by decorating the Seder plate with gold and silver. They do this to remember how the Jews left Egypt with riches.
