Yule Log

December’s challenge was just right for the season- A Yule Log! Lis of La Mia Cucina and Ivonne of Cream Puffs in Venice selected Nick Malgieri’s Buche de Noel from Perfect Cakes and The Williams-Sonoma Collection: Dessert). A genoise sponge, free for all filling, buttercream icing and meringue or marzipan mushrooms do not make for an easy initiation.

I first decided on the components of my yule log- I opted for a coffee pudding filling and a chocolate flavored genoise. I figured the pudding would be a great way of using up some of the extra egg yolks. The genoise, which I made with some trepidation turned out okay. I think I lost a little volume while folding in the dry ingredients but it came out light enough. Gone is my fear of genoise!

While warm, I rolled up the chocolate genoise with a kitchen towel as I would do with the jelly rolls I made. Then I attacked the butter cream. I chose to use dark chocolate and crème de cacao instead of coffee. I took extra care to make sure it didn’t break following all the wise advise available. I felt though that the color was still too pale.

Then came one of the best parts…making the meringue mushrooms. They are so cute that whatever fatigue I was experiencing after 6 hours dissipated once these lovely creations came out of the oven!

Then came the assembly. I filled and frosted my roll taking care to add the little branch on the top. I still didn’t like the color of my log. So I melted some dark chocolate and spread it on a baking sheet. I broke this into strips and then I covered up my roll and tried to make it look like bark. I succeeded in some areas but it wasn’t as neat as I had hoped.

With all the mushrooms sticking out and the crumbly chocolate bark, I am loathe to slice this pretty cake!

Buche de Noel:

Plain Genoise:

3 large eggs
3 large egg yolks
pinch of salt
¾ cup of sugar
½ cup cake flour - spoon flour into dry-measure cup and level off (also known as cake & pastry flour)
¼ cup cornstarch

one (1) 10 x 15 inch jelly-roll pan that has been buttered and lined with parchment paper and then buttered again

1.Set a rack in the middle of the oven and preheat to 400 degrees F.

2.Half-fill a medium saucepan with water and bring it to a boil over high heat. Lower the heat so the water is simmering.

3.Whisk the eggs, egg yolks, salt and sugar together in the bowl of a heavy-duty mixer. Place over the pan of simmering water and whisk gently until the mixture is just lukewarm, about 100 degrees if you have a thermometer (or test with your finger - it should be warm to the touch).

4.Attach the bowl to the mixer and, with the whisk attachment, whip on medium-high speed until the egg mixture is cooled (touch the outside of the bowl to tell) and tripled in volume. The egg foam will be thick and will form a slowly dissolving ribbon falling back onto the bowl of whipped eggs when the whisk is lifted.

5.While the eggs are whipping, stir together the flour and cornstarch.

6.Sift one-third of the flour mixture over the beaten eggs. Use a rubber spatula to fold in the flour mixture, making sure to scrape all the way to the bottom of the bowl on every pass through the batter to prevent the flour mixture from accumulating there and making lumps. Repeat with another third of the flour mixture and finally with the remainder.

7.Scrape the batter into the prepared pan and smooth the top.

8.Bake the genoise for about 10 to 12 minutes. Make sure the cake doesn’t overbake and become too dry or it will not roll properly.

9.While the cake is baking, begin making the buttercream.

10.Once the cake is done (a tester will come out clean and if you press the cake lightly it will spring back), remove it from the oven and let it cool on a rack.

Coffee Buttercream:

4 large egg whites
1 cup sugar
24 tablespoons (3 sticks or 1-1/2 cups) unsalted butter, softened
2 tablespoons instant espresso powder
2 tablespoons rum or brandy

1.Whisk the egg whites and sugar together in the bowl of an electric mixer. Set the bowl over simmering water and whisk gently until the sugar is dissolved and the egg whites are hot.

2.Attach the bowl to the mixer and whip with the whisk on medium speed until cooled. Switch to the paddle and beat in the softened butter and continue beating until the buttercream is smooth. Dissolve the instant coffee in the liquor and beat into the buttercream.


Meringue Mushrooms:

3 large egg whites, at room temperature
¼ teaspoon cream of tartar
½ cup (3-1/2 ounces/105 g.) granulated sugar
1/3 cup (1-1/3 ounces/40 g.) icing sugar
Unsweetened cocoa powder for dusting

1.Preheat the oven to 225 degrees F. Line 2 baking sheets with parchment. Have ready a pastry bag fitted with a small (no. 6) plain tip. In a bowl, using a mixer on medium-low speed, beat together the egg whites and cream of tartar until very foamy. Slowly add the granulated sugar while beating. Increase the speed to high and beat until soft peaks form when the beaters are lifted. Continue until the whites hold stiff, shiny peaks. Sift the icing sugar over the whites and, using a rubber spatula, fold in until well blended.

2.Scoop the mixture into the bag. On one baking sheet, pipe 48 stems, each ½ inch (12 mm.) wide at the base and tapering off to a point at the top, ¾ inch (2 cm.) tall, and spaced about ½ inch (12 mm.) apart. On the other sheet, pipe 48 mounds for the tops, each about 1-1/4 inches (3 cm.) wide and ¾ inch (2 cm.) high, also spaced ½ inch (12 mm.) apart. With a damp fingertip, gently smooth any pointy tips. Dust with cocoa. Reserve the remaining meringue.

3.Bake until dry and firm enough to lift off the paper, 50-55 minutes. Set the pans on the counter and turn the mounds flat side up. With the tip of a knife, carefully make a small hole in the flat side of each mound. Pipe small dabs of the remaining meringue into the holes and insert the stems tip first. Return to the oven until completely dry, about 15 minutes longer. Let cool completely on the sheets.


Marzipan Mushrooms:

8 ounces almond paste
2 cups icing sugar
3 to 5 tablespoons light corn syrup
Cocoa powder

1.To make the marzipan combine the almond paste and 1 cup of the icing sugar in the bowl of an electric mixer and beat with the paddle attachment on low speed until sugar is almost absorbed.

2.Add the remaining 1 cup of sugar and mix until the mixture resembles fine crumbs.

3.Add half the corn syrup, then continue mixing until a bit of the marzipan holds together when squeezed, adding additional corn syrup a little at a time, as necessary: the marzipan in the bowl will still appear crumbly.

4.Transfer the marzipan to a work surface and knead until smooth.
