Chocolate Roulade |
Ingredients
Chocolate
Sponge Cake:
6 large eggs, separated
4 ounces (120 grams) semisweet chocolate, chopped
1/4 cup (50 grams) plus 2 tablespoons (30
grams) granulated white sugar
1 teaspoon pure vanilla extract
3/4 teaspoon cream of tartar
Whipped
Cream Filling:
1 cup (240 ml) cold heavy whipping cream
(double cream) (40% butterfat content)
1/2 teaspoon pure vanilla extract
1 tablespoon (15 grams) granulated white
sugar
Chocolate
Ganache:
100 ml cooking cream
100 gms dark chocolate
Chocolate Sponge Cake: Preheat oven to 140
degrees C and place the oven rack in the center of the oven. Butter, or spray
with a non stick vegetable spray, a 15 by 12 inch sheet pan. Line the pan with
parchment paper and then butter and flour the paper (or spray with
vegetable/flour spray.
While the eggs are still cold, separate the
eggs, placing the whites in one bowl and the yolks in another. Cover with plastic
wrap and bring to room temperature before using (takes about 30 minutes).
Meanwhile melt the chocolate in a stainless
steel bowl placed over a saucepan of simmering water. Let cool to room
temperature.
In the bowl of your electric mixer (or with a
hand mixer) place the egg yolks and 1/4 cup (50 grams) of sugar and beat, on
high speed, until this mixture is thick, light and fluffy (about five minutes).
(When you slowly raise the beaters, the batter will fall back into the bowl in
a slow ribbon.) Beat in the vanilla extract. Add the melted chocolate and beat
only to combine. Set aside while you beat the egg whites.
In a clean mixing bowl, with the whisk
attachment, beat the egg whites until foamy. Add the cream of tartar and beat
at medium-high speed until soft peaks form. Gradually beat in the remaining 2
tablespoons (30 grams) of sugar until stiff peaks form.
Gently fold a small amount of the egg whites
into the egg yolk mixture using a rubber spatula or whisk to lighten the
batter. Fold in the remaining whites just until incorporated. (Don't over mix or the batter will deflate.)
Spread the batter evenly into the prepared pan with the back of a spoon, or an
offset spatula. Bake until the cake is puffed, has lost its shine, and springs
back when gently pressed, about 10 - 12 minutes (do not overbake, the cake
bakes quickly). Remove from oven and place on wire rack to cool. Cover the cake
with a clean, slightly damp towel.
Whipped Cream Filling: Place your mixing bowl
and whisk attachment in the freezer for 15 minutes. Then place the whipping
cream, vanilla extract, and sugar into the bowl and beat until soft peaks form.
Once the cake has cooled, spread with the whipped cream and gently roll the
cake, peeling off the parchment paper as you roll.
For the Ganache: melt chocolate in the
microwave for 10 seconds. Pour warm cream and mix gently. Spread ganache over
the rolled cake.
Can be covered and stored in the refrigerator
for up to five days.
