The History And Symbolism Of Matzo Balls.

Matzo ball soup with dill. Matzo represents the unleavened bread the Jews ate while fleeing Egypt.

Nothing says Passover like a good bowl of matzo ball soup. That's according to Joan Nathan, chef and grande-dame of Jewish cooking, who spoke to Steve Inskeep of NPR's Morning Edition about the importance of the tradition.

The Jewish holiday of Passover celebrates the Biblical story of the Exodus, or the freeing of Hebrew slaves from Egypt.

"It's really the defining story of Judaism. Everybody in some way can identify with it – Jewish or not," says Nathan,

The Passover meal, known as a Seder, is all about remembering Jewish history. Much of the food is deeply symbolic. Matzo represents the unleavened bread the Jews ate while fleeing Egypt, for example, and horseradish is a symbol for the bitterness of slavery.

But the dumplings were not always called matzo balls. They were called knoedel, Nathan says, and the Germans, Austrians and Alsatians used them in soups. When Jews moved to Poland, they referred to them as knoedela, and in the 1930s, the U.S. Manischewitz company started packaging the product and called them "Alsatian feathery balls." Nathan says it was probably U.S. comedians and vaudeville performers that finally dubbed them "matzo balls."

Recipe: Joan Nathan's Matzo Ball Soup

2 tablespoons rendered chicken fat

4 large eggs

1/4 cup chicken broth or water

3 teaspoons salt

Freshly ground pepper to taste

1 teaspoon freshly grated ginger or 1/2 teaspoon powdered ginger

1/4 teaspoon grated nutmeg

1 cup matzo meal

Put the chicken fat, eggs, broth or water, 2 teaspoons salt, freshly ground pepper, the ginger and the nutmeg in a medium mixing bowl. Stir well with a wooden spoon, then add the matzo meal and stir just until mixed. Cover and refrigerate for at least an hour, or overnight.

Bring a large pot of water with the remaining teaspoon of salt to a boil. Set a small bowl of cold water next to your work space. Dip your hands in the water, then form matzo balls about the size of small walnuts. Drop the matzo balls into the boiling water, then cover and simmer for about 20 minutes, or until al dente.

Yield: About 10 matzo balls

Note: There are two ways that one can render the fat. The first way is to take the fat off the chicken and melt it down in a frying pan with onions. The second and easiest method is to make chicken soup (using the skin), then cool and refrigerate the soup overnight, and spoon off the fat that accumulates on top.
