This month has been a busy month, but I'm so excited about my new challenge! While reading my fellow cooking contest buddies sites I noticed that some participate in a monthly challenge with a group called The Daring Bakers. Each month, one member of the group selects a baking recipe and challenges the other members to attempt the recipe exactly as written which you then write about the recipe on their individual sites. The chosen recipe is to remain top secret among members only until the last day of the month, at which time the bakers can share their experiences, along with any photos that they took, with their readers.
I must admit when I saw the challenge I thought - What in the heck did I sign up for? Oh geez this is gonna be a doozy! Filbert Gateau with Praline Buttercream, I can't even say that how am I gonna make it? I printed my recipe and read a couple of the post from other bakers and it seems that this is a 2-3 day breakdown to get it all done correctly. I also admit that this is probably one of those recipes that look gorgeous in the cookbook, but I would pass it up with all the steps, but I signed up for this to challenge myself and that's exactly what I did.
This months challenge was brought to us by Chris of Mele Cotte. He chose a beautiful Filbert Gateau with Praline Buttercream from Great Cakes by Carol Walter. I had to look a couple of things up first before I started. Filbert is a species of Haxel native to southeastern Europe and southwestern Asia. Ok check, that makes sense since the cake is traditionally made with Hazelnuts. Gateau is cake. Ok, I'm feeling better about this recipe already woohoo!
Alright so on to the recipe....
Filbert Gateau with Praline Buttercream
Filbert Genoise
1 ½ cups hazelnuts, toasted/skinned pecans
1 tsp. vanilla extract
Position rack in the lower 3rd of the oven and preheat to 350 degrees. Grease and flour a 10” X 2” inch round cake pan. I used 2 8" pans, filling 1 pan 3/4 full and the 2nd 1/4 full. You could probably just use 1 pan but for me it was easier using 2 instead of cutting 3 layers.
Using a food processor, process nuts, cake flour, and cornstarch for about 30 seconds. Then, pulse the mixture about 10 times to get a fine, powdery mixture. You’ll know the nuts are ready when they begin to gather together around the sides of the bowl. While you want to make sure there aren’t any large pieces, don’t over-process. Set aside.
**Cream Cheese Filling
Cream together all ingredients.
Praline Paste
1 cup (4 ½ oz.) Hazelnuts, toasted/skinless pecans
2/3 cup Sugar
Line a jelly roll pan with parchment and lightly butter.
Put the sugar in a heavy 10-inch skillet. Heat on low flame for about 10-20 min until the sugar melts around the edges. Do not stir the sugar. Swirl the pan if necessary to prevent the melted sugar from burning. Brush the sides of the pan with water to remove sugar crystals. If the sugar in the center does not melt, stir briefly. When the sugar is completely melted and caramel in color, remove from heat. Stir in the nuts with a wooden spoon and separate the clusters. Return to low heat and stir to coat the nuts on all sides. Cook until the mixture starts to bubble. **Remember – extremely hot mixture. 320 degrees** Then onto the parchment lined sheet and spread as evenly as possible. As it cools, it will harden into brittle. Break the candied nuts into pieces and place them in the food processor. Pulse into a medium-fine crunch or process until the brittle turns into a powder. To make paste, process for several minutes. Store in an airtight container and store in a cook dry place. Do not refrigerate.
Apricot Glaze
Good for one 10-inch cake
2/3 cup thick apricot preserves I used mango/peach preserves
1 Tbsp. water
In a small, yet heavy saucepan, bring the water and preserves to a slow boil and simmer for 2-3 minutes. If the mixture begins to stick to the bottom of the saucepan, add water as needed.
Remove from heat and, using a strainer, press the mixture through the mesh and discard any remnants. With a pastry brush, apply the glaze onto the cake while the cake is still warm. If the glaze is too thick, thin to a preferred consistency with drops of water.
Ganache Glaze
Makes about 1 cup, enough to cover the top and sides of a 9 or 10 inch layer or tube cake
**Ganache can take on many forms. While warm – great fudge sauce. While cool or lukewarm – semisweet glaze. Slightly chilled – can be whipped into a filling/frosting. Cold & solid – the base of candied chocolate truffles.
6 oz. (good) semisweet or bittersweet chocolate, like Lindt
6 oz. (¾ cup heavy cream1 tbsp. light corn syrup
1 Tbsp. Grand Marnier, Cointreay, or dark Jamaican rum (optional) Amaretto Liqueur
¾ tsp. vanilla
½ - 1 tsp. hot water, if needed
Blend vanilla and liqueur/rum together and set aside. Break the chocolate into 1-inch pieces and place in the basket of a food processor and pulse until finely chopped. Transfer into a medium sized bowl and set aside.
Heat the cream and corn syrup in a saucepan, on low, until it reached a gentle boil. Once to the gently boil, immediately and carefully pour over the chocolate. Leave it alone for one minute, then slowly stir and mix the chocolate and cream together until the chocolate is melted and incorporated into the cream. Carefully blend in vanilla mixture. If the surface seems oily, add ½ - 1 tsp hot water. The glaze will thicken, but should still be pourable. If it doesn’t thicken, refrigerate for about 5 minutes, but make sure it doesn’t get too cold!
Assembling Cake
Cut a cardboard disk slightly smaller than the cake. Divide the cake into 3 layers and place the first layer top-side down on the disk. Using a pastry brush, moisten the layer with 3-4 Tbsp. of warm sugar syrup. Measure out 1 cup of praline buttercream and set aside.
Spread the bottom layer with a ¼-inch thickness of the remaining buttercream. Cover with ½ of the whipped cream, leaving ¼-inch border around the edge of the cake. Place the middle layer over the first, brush with sugar syrup, spreading with buttercream. Cover with the remaining whipped cream.
Moisten the cut side of the third layer with additional sugar syrup and place cut side down on the cake. Gently, press the sides of the cake to align the layers. Refrigerate to chill for at least 30 minutes.
Lift the cake by sliding your palm under the cardboard. Holding a serrated or very sharp night with an 8-ich blade held parallel to the sides of the cake, trim the sides so that they are perfectly straight. Cut a slight bevel at the top to help the glaze drip over the edge. Brush the top and sides of the cake with warm apricot glaze, sealing the cut areas completely. Chill while you prepare the ganache.
Place a rack over a large shallow pan to catch the ganache drippings. Remove the gateau from the refrigerator and put it the rack. With a metal spatula in hand, and holding the saucepan about 10 inches above the cake, pour the ganache onto the cake’s center. Move the spatula over the top of the ganache about 4 times to get a smooth and mirror-like appearance. The ganache should cover the top and run down the sides of the cake. When the ganache has been poured and is coating the cake, lift one side of the rack and bang it once on the counter to help spread the ganache evenly and break any air bubbles. (Work fast before setting starts.) Patch any bare spots on the sides with a smaller spatula, but do not touch the top after the “bang”. Let the cake stand at least 15 minutes to set after glazing.
To garnish the cake, fit a 12 – 14-inch pastry bag with a #114 large leaf tip. Fill the bag with the reserved praline cream. Stating ½ inch from the outer edge of the cake, position the pastry tube at a 90 degree angle with the top almost touching the top of the cake. Apply pressure to the pastry bag, moving it slightly toward the center of the cake. As the buttercream flows on the cake, reverse the movement backward toward the edge of the cake and finish by pulling the bag again to the center. Stop applying pressure and press the bag downward, then quickly pull the tip up to break the flow of frosting. Repeat, making 12 leaves evenly spaced around the surface of the cake.
Make a second row of leaves on the top of the first row, moving the pastry bag about ¾ inch closer to the center. The leaves should overlap. Make a 3rd row, moving closer and closer to the center. Add a 4th row if you have the room. But, leave a 2-inch space in the center for a chopped filbert garnish. Refrigerate uncovered for 3-4 hours to allow the cake to set. Remove the cake from the refrigerator at least 3 hours before serving.
Leftover cake can be covered with foil and kept in the refrigerator for up to 5 days.
