Four cups of wine. Veggies dipped in saltwater. Matzah. Bitter herbs, often horseradish (without additives) and romaine lettuce, dipped into charoset (a paste of nuts, apples, pears and wine). And a festive meal. Ceremonial foods are all arranged on a platter, called a ka'arah or Seder plate. There is one ka'arah on the Seder table. The procedure is all laid out in a book called a Haggadah, Although the text is in Hebrew (with a sprinkling of Aramaic), it is perfectly acceptable to read the Haggadah in translation if you don't understand Hebrew.
