HUNGARIAN CHOCOLATE WALNUT TORTE

Steps:

• Have all ingredients at room temperature. Line the bottom of an 8-inch square cake pan or a 9-inch spring form pan with parchment or wax paper. Preheat the oven to 350°F.
• In a heavy-bottomed 2-or 3-quart saucepan, combine 1/2 cup of the sugar and 1/2 cup water and bring to a boil, stirring constantly over medium heat. Continue boiling and stirring until all the grains of sugar have completely dissolved and the mixture forms a simple syrup. Remove the pan from the heat and stir in the chocolate until melted and smooth. Set aside to cool.
• In a large bowl, beat the egg yolks with an electric mixer until light and thickened, about 4 minutes. Grind the walnuts with the remaining sugar and the matzoh meal in a food processor using the pulse motion and stir into the egg yolks. Add the cooled chocolate mixture and combine thoroughly.
• Using clean beaters, beat the egg whites in another bowl until they hold stiff peaks. Gradually fold the whites into the chocolate-walnut mixture, incorporating them gently but thoroughly so that no whites are visible.
• Pour the batter into the prepared pan and bake for 30 to 40 minutes, until puffed and almost set but still a little gooey in the center. A wooden toothpick inserted 1 inch from the edge should come out clean.
• Remove the pan from the oven and let cool on a rack. When completely cool, unmold the cake by running a thin-bladed knife around the edges of the cake to release it from the pan (or release the spring form); invert onto a platter. Peel off the parchment paper. Serve the torte at room temperature.
• Glaze with the chocolate icing. Lay long strips of wax paper or foil on a cake plate or serving platter and place the cake on top. Pour the glaze over the top of the cake, letting it drip down the sides.
• Using a spatula, evenly spread the glaze over the top and sides. Now, pull out and discard the paper strips or foil strips--the plate will be clean and ready for serving. If you'd like, garnish with a few walnut halves attractively placed in the center of the cake. Refrigerate the cake for about an hour to set the glaze, but bring it to room temperature before serving.
• OR if desired, lightly dust with Passover confectioners' sugar. For a lovely, simple presentation, place a doily or a stencil-handmade by you or, even better, your children-over the torte, then sprinkle with the sugar. Carefully remove the doily or stencil.
• The plain or frosted torte is heavenly with generous dollops of whipped cream or vanilla ice cream.
• Passover Confectioners Sugar: In a blender, mini-food processor, or clean coffee grinder, whirl 1 cup minus 1/2 tablespoon regular granulated sugar until it is powdery. Place in a small bowl and stir in 1/2 teaspoon potato starch. Sift before using. (Recently commercial Passover confectioners' sugar, made without cornstarch, has appeared in some stores with large kosher-for-Passover sections. If available, by all means use it here.)
• Chocolate Icing: Melt the butter or margarine slowly in a heavy saucepan over very low heat. When half is melted, gradually whisk in the chocolate, stirring well as it melts. After all the chocolate has been added, stir in 2 tablespoons water and beat well until the glaze is completely smooth. Let the mixture cool about 5 minutes to thicken slightly.
