100 g strawberry jam or marmalade, preferably with pieces of fruit
240 g heavy cream 35% fat
15 g granulated sugar
70 g pistachio nuts, crushed
200 g dark chocolate couverture
100 g heavy cream 35% fat
Preheat oven to 180* C (350* F) Fan.
Beat the egg yolks and 50 g of sugar in a mixer, using the whisk attachment, until the mixture becomes lighter in color and fluffy.
Melt the chocolate in a bain marie or a microwave. When it has melted and cooled, add to the egg yolk mixture and beat to combine.
In a clean bowl, beat the egg whites with the whisk attachment, on low speed. Add the salt and mix. Add the 30 g of sugar. Increase the speed and beat until you create a meringue.
Combine ¼ the meringue with the egg yolk mixture to make the mixture lighter and fluffier. Add the remaining meringue in 3 batches and gently fold in with a spatula. It’s alright if there are a few parts where the meringue has not been completely incorporated. You do not want to overmix.
Line a 30×40 cm baking pan with parchment paper. Grease the parchment with butter and dust with cocoa powder so the mixture does not stick.
Spread mixture into pan and bake for 15-17 minutes.
When ready, remove from oven and cover with a damp towel. Set aside to cool like this so that the sponge cake does not dry out and it will be easier to roll.
Prepare the filling by beating the heavy cream and sugar in a mixer until they become whipped cream. When ready, add the marmalade or jam and mix to distribute.
Prepare the ganache coating by heating the heavy cream in a saucepan and then pouring it over the chopped chocolate.
Stir until the chocolate melts and the mixture is smooth and completely combined. Set aside for a few minutes so it can cool.
Cut the edges off of the sponge cake. They are crunchy and will be difficult to roll.
Spread the filling over the sponge cake. Leave a 4-5 cm border on the opposite end of the side you are going to start rolling.
Roll into a log. You can cut off 2 pieces to use for decorative purposes.
Spread the ganache over the log and decorate in any way you like.
Drag a fork over the log to give it the appearance of an actual tree log.
