Celebration Cake. This one got me upset when I thought I had left the recipe behind in all those
mags I gave away. I patted myself on the shoulder when I found that I had photocopied it. So now I've converted it. Whew! So glad you asked.
This is really a beautiful cake, that people have a hard time believing to be homemade. They ooh and aah over and that they really don't want to eat cuz it's pretty. And so so delicious. Not something you whip up in a moment though.
CELEBRATION CAKE
BON APPETIT - MAY 1979, ..... 8 to 10 servings
8 ounces shelled hazelnuts, toasted
8 ounces blanched almonds, toasted
1 cup sugar
1/4 cup all purpose flour
8 egg whites, room temperature
1/3 teaspoon cream of tartar
1/3 teaspoon salt
1/4 cup sugar
1 tablespoon water
1/4 cup slivered almonds
Buttercream
1 cup sugar
1/3 cup water
8 egg yolks, room temperature
1 ½ cups (3 sticks) unsalted butter, room temperature
1 teaspoon vanilla
3 ounces semisweet chocolate, melted and cooled
Sifted powdered sugar
Preheat oven to 350'F. Generously grease and flour 10x15-inch jelly roll pan. Combine 5 ounces hazelnuts and 5 ounces almonds in food processor fitted with steel knife and process until finely ground. Transfer to small mixing bowl. Reduce oven temperature to 300°F.
Add 3/4 cup sugar and all of flour to ground nuts and blend well. In large bowl beat egg whites until foamy. Add cream of tartar and salt and continue beating until soft peaks form. Slowly add remaining 1/4 cup sugar and beat until stiff but not dry. Gently fold nut mixture, 2 tablespoons at a time, into whites, blending thoroughly. Carefully turn batter into prepared pan, spreading evenly to edges. Bake 45 minutes. Meringue should be firm, dry and lightly golden; if not, turn off heat and return to oven for 5 to 10 minutes. Remove from oven and cool slightly. Using serrated knife, cut into four 10 x 3 3/4-inch rectangles. Cool completely in pan.
Generously oil marble slab or baking sheet. Combine 1/4 cup sugar with 1 tablespoon water in small heavy-bottomed saucepan. Place over medium heat and stir until sugar is dissolved. Reduce heat to low and continue cooking without stirring until mixture begins to caramelize, tilting pan in all directions to avoid scorching. When completely caramelized and golden, stir in slivered almonds. Pour onto prepared slab or baking sheet and allow to cool completely. Break into pieces and pulverize in food processor or blender. Set this praline powder aside.
Finely chop remaining nuts in food processor. Set aside for garnish.
For Buttercream:
Combine 1 cup sugar and 1/3 cup water in small saucepan and mix well. Cover pan, place over high heat arid bring to boil. Reduce heat to medium and continue boiling, covered, 1 to 2 minutes. Remove cover and place candy thermometer into saucepan. If necessary, use damp brush or paper towel to wipe sugar crystals from side of saucepan. Boil uncovered until syrup reaches soft-ball stage (240 F).
Using electric mixer on low speed, begin beating yolks in large bowl while syrup boils. Leave mixer running while removing syrup from heat. Increase mixer speed to medium or medium-high and slowly pour syrup directly into yolks, being careful not to pour syrup onto sides of bowl or onto beaters. When all syrup is added, increase mixer speed to high and continue beating until completely cooled. When cool, reduce mixer speed to medium and begin adding butter 1 tablespoon at a time, beating well after each addition. When all butter is incorporated, increase mixer speed to high and continue beating until creamy and thoroughly blended.
Remove 1 cup buttercream to separate bowl. Add vanilla and blend well. Set aside. Remove additional 3/4 cup buttercream to another bowl. Add 1/4 - 1/2 cup praline powder and blend well. Set aside. Beat cooled chocolate into remaining buttercream and blend well.
Carefully remove meringue rectangles from jelly roll pan using long spatula. Place 2 meringue layers side by side on baking sheet. Top one layer with praline buttercream mixture, spreading evenly to edges. Cover top of second layer evenly with vanilla buttercream mixture. Place remaining 2 meringue layers side by side on another baking sheet. Spread one layer with 1 cup chocolate buttercream mixture. Leave remaining layer unfrosted. Place layers in refrigerator for 5 to 10 minutes, or until fillings are slightly firm, but not hard.
To assemble:
With filling sides up, place praline layer on bottom, then chocolate layer, then vanilla layer. Set unfrosted meringue layer on top, smooth side up. Gently press down top of cake to seal layers. Frost sides of cake using remaining chocolate buttercream (do not frost top). Press reserved nuts gently into sides. Generously dust top with powdered sugar. Refrigerate. Transfer to platter and serve cool (filling should be firm but not hard). Cut with serrated knife.
If additional decoration is desired, increase buttercream recipe by one-third.
Any remaining praline powder can be stored in refrigerator indefinitely in tightly closed jar. Excellent over ice cream.
