She will make about nine challot for Shabbat, when she and her husband, Rabbi Avraham Jacobovitz of Machon L'Torah, will host at least 20 guests, as they do each Friday night. Many say they wait from Friday to Friday just to eat Bayla Jacobovitz's challah. As the deep blue of the Jerusalem night is replaced by daylight, the bakers begin slowly to shed their white uniforms. Soon they will go home. Then the crowds will come: Israelis from everywhere, all here to buy challah. Thousands of miles away and eight hours later, Bayla Jacobovitz pours yeast and warm water into a large Down the corner and to the left of the Jacobovitzs' home, Zeman's New York Kosh6r Bakery also is preparing for Shabbat. By Friday after- noon, more than 2,000 loaves of bread will have been baked to sell that one day. From generation to generation, Jewish homes have been filled with the aroma of fresh bread for Shabbat. Two loaves, sym- bolizing the double portion of manna the Israelites in the desert received each Fri- day, are placed on the Shabbat table. It may appear as little more than a simple loaf, but bread must be treated with respect, the rabbis taught. It is covered during Kiddush to spare it "embarrassment" because its bracha, blessing, follows that of wine. Bread may not touch raw meat or be tossed across the table. To keep bread from the poor is called a sin, while providing it to the needy is regarded a moral obligation. In the Torah, the idolater Micah was promised a place in the world to come because he had given bread to the poor.

The aroma flows past the home of the rabbi who stops motorists on Shabbat and says, "Please don't drive to- day! Come have tea with me and I will tell you magical stories of the world to come!" and past the dusty bookstores that hold volumes about the life of the great scholar Rab- bi Akiva. Most of Jerusalem is sleep- ing. The bakers are not. Their work has just begun. Each Thursday night, they come to make challah. Framed by a dim orange light near the hot ovens, they knead the dough. Thousands of loaves — with poppy seeds, with a braid on top, in a circle, with sesame seeds — are created. 26 FRIDAY, NOVEMBER 24,198 W hen she moved from New York to Oak Park, Bayla Jacobovitz brought her mother's and grandmother's challah recipe, which she always had prepared with great success. - But she didn't like the taste of the bread when she made it here, she says. Sometime later, a student from Machon L'Torah asked to make challah at her house. His bread, she says, was delicious. That's when Jacobovitz discovered another recipe, which friends called "the recipe that always works." She uses it to this day. Just as Shabbat is the seventh day of the week, this recipe has seven ingredients, Jacobovitz notes. 6 packages of yeast 5 cups warm water 1 1/3 cup sugar 1 1/3 cup oil 6 beaten eggs 8 tablespoons salt 20 cups flour Dissolve yeast in water.
