Week 10: Chocolate Swiss Roll

It was another busy week with the chocolate swiss rolls.  I had a substitute partner this week, who was there from another class, so it was nice to share the workload.


The cake part of this recipe was fairly simple with only 4 ingredients: eggs, sugar, cocoa and flour.  We started by making an egg foam with the eggs and sugar, this was whisked until it really increased in volume.  The flour and cocoa was folded in by hand to ensure the egg foam didn't deflate or over mix.

With an egg foam batter, it is important to work quickly as the batter is continuously deflating until it is in the oven.

The batter was baked on a large sheet pan covered in parchment paper.  Baking a thin cake allows for easy rolling but I also think it leads to the cake baking slightly dry, but this can be fixed with lots and lots of simple syrup.

Next was the chocolate glaze.  We boiled some heavy cream with glucose and added that to dark chocolate.  The glucose was added to make the chocolate glossy.  This was set aside to cool while we made the Italian chocolate buttercream to go inside the roll.

The buttercream was my favourite part!  I'm never going back to the standard American Buttercream made with just butter and icing sugar again.

With Italian buttercream, since the sugar is cooked and slowly added to the whipped egg whites, the icing turns out much smoother.  Adding lots of butter, makes it very silky.

Before spreading the icing, I brushed a heavy amount of brandy flavoured simple syrup over the entire cake to keep it moist.  The buttercream was spread fairly thinly over the cake, but next time, I will spread it even thinner since it makes the rolling much easier.

I sprinkled a few raspberries and toasted hazelnuts inside, then rolled up the cake.  Once I made the rolling as tight as possible, I masked it with more buttercream :)  Last step was to drizzle chocolate glaze on top and decorate with chocolate accents, raspberries and hazelnuts.

Since I made the mistake of piping buttercream onto chocolate glaze that wasn't fully cooled, my buttercream rosettes slipped off of one of the swiss rolls and I had to redecorate.  This is how it turned out...
