Happy Rosh Hashanah! Have you made your challah yet? Challah is typically made as a long, braided loaf, its crust a shiny golden brown from a glaze of beaten egg applied before baking. But Rosh Hashanah challah, which celebrates the Jewish new year, often appears in a spiral — signifying the circle of life. This particular challah is studded with fresh apple and raisins, and rolled in an aromatic coating of cinnamon-sugar — autumn flavors to complement the September Rosh Hashanah holiday.
