Thank you, Ria and Jamie, for hosting a pleasant, original challenge! Please check out the Daring Kitchen for the challenge recipes, and the Daring Bakers’ blogroll to see what all the other bakers concocted this month!
Actually, it didn’t explode: it erupted. Originally, this flourless chocolate cake is called a Torta alla Caprese, popularized in Quebec by the fabulous Josée di Stasio – but after this ordeal, we have renamed it Mount Vesuvius (you know, the volcano).
Laurent and I have often made this cake together. It’s often our go-to recipe when we need to bring dessert for a potluck. It’s both fluffy and rich, always moist, it keeps like a dream, and contains enough dark chocolate and caffeine to keep you jittery all night long. If I had to take one chocolate recipe with me on a desert island, this might just be it.
The Torta alla Caprese is also very simple to make. It has never let us down before, so I’m really quite confused about what happened this time. As the cake baked, the batter rose so much that it completely overflowed from the mould and covered it entirely. Laurent has been known to be a little heavy-handed with the baking powder, but this was ridiculous.
Well, a major trim with a small knife was enough to make the cake look just about normal again (and we got to eat all the leftover trimmings, tee hee). The people at the potluck never knew they were eating a wannabe-volcano.
Sorry for the poor quality of the picture, but we were in a hurry. I also wish I had a picture of a slice, so I could show you the cake’s wonderful texture. But it never made it back from the potluck, so you’ll just have to trust me: this torta is a pure delight. Go make it. Now.
The recipe is available here in French, but here’s a loose translation:
Torta alla Caprese
From Josée di Stasio’s Pasta et Cetera
Serves 8 to 10
200g (7 0z) dark chocolate, chopped
200g / 250ml (7 oz / 1 cup) butter
60ml (1/4 cup) espresso
280g / 500ml (9.5 oz / 2 cups) almond meal
1 tbsp baking powder
190g / 250ml sugar
5 large eggs
Cocoa or icing sugar, for dusting
Preheat oven to 180 ºC (350 ºF). Butter and flour a 25cm (10 inch) pie mould with a removable bottom.
In a double boiler, melt the butter and chocolate. Remove from heat, add the espresso and let cool.
In a medium bowl, combine the almond meal and the baking powder. Reserve.
In a large bowl, with an electric beater, whisk the whole eggs with the sugar until primrose in colour, about 5 minutes. Incorporate the almond mixture. Then incorporate the chocolate mixture.
Pour mixture into the prepared mould. Bake about 40 minutes, until the cake is firm to the touch. It will solidify further as it cools, so don’t worry if the center still looks a tad soft. Let cool in mould for at least 4 hours.
Dust with icing sugar or cocoa before serving.
I stuck to the original recipe, because absolutely everything was new to me. For one thing, I had never made sponge cake. Génoise, yes, but not sponge cake – the difference being, as I recently discovered, that for génoise the eggs are beaten whole with sugar, whereas they are separated for sponge cake. The recipe gave us the following technique for making regular sponge cake layers: draw a circle on a sheet of parchment paper (using a template), spread a thin layer of batter within the limits of each circle, and bake for 5 minutes per baking sheet. Then, the layers had to be trimmed to down to equal diameters with the help of a pie tin or some other circular object. I wonder if it would have been easier to bake each layer directly in a parchment-lined pie tin, in order to obtain fool-proof regular circles…
Well, at any rate, the tracing method worked well enough, and I was pleasantly surprised by the texture of the sponge cake: quite sticky (peeling it off the parchment was a little tricky), but solid (even in my clumsy hands, it didn't come close to tearing). I could tell the layers would be good for stacking. I actually ended up with eight layers, instead of the predicted six, because I used a slightly smaller diameter.
I had never made buttercream, either. At least not this type, which required whisking eggs over a double boiler until thickened, adding chocolate, then incorporating butter when cooled (does that make it a German buttercream?). I cooked my eggs and chocolate mixture for longer than indicated, because it didn’t seem to be thickening. In fact, I worried about the result being too liquid until the very last stage, when the butter finally turned the runny mixture into a creamy, thick frosting that was just begging to be licked off the spoon.
And finally, there was the toffee. The task was to slice one of the sponge cake layers into portions, then pour hot caramel over it, spread it around and cut through it quickly, so as to obtain separate toffee-covered cake pieces, to decorate the top of the Dobos. Having burnt my fair share of caramel in the past, I erred on the side of caution this time, and didn’t cook the caramel long enough. As a result, it was too liquid when I poured it over the cake.
I looked at my cake portions as they bathed in the liquid-caramel-filled cake pan I had placed them in. I fully expected them to turn soggy and dissolve – but they didn’t. Instead, the caramel very slowly solidified… under the cake pieces. So, in the end, I wound up with more or less what I was aiming for, just upside down (which was easy enough to fix, obviously). Well, the toffee was definitely too chewy and nearly impossible to eat at first, but a night in the fridge hardened it a bit.
I made a rookie mistake while assembling the cake: I put more frosting at the center of the layers than at the edges, resulting in a domed cake. So, of course, when I put the toffee pieces on top of the final frosted layer, they started to slip. So I did what I always do when something in the kitchen starts to slip, stick, or tear: I tried to keep everything in place as best as I could, while screaming for Laurent to get me something – in this case, aluminum foil. We formed a cylinder around the cake to hold it together, then let it set in the fridge. No fancy decorations this time, I was just happy it looked more or less normal.
Knowing how much buttercream I’d smeared over and inside it, I was expecting the Dobos to be really heavy on the stomach, but it wasn’t: I actually find ganache-covered cakes to be much heavier. This buttercream very much reminded of the kind used on bûche de Noël: not too strong, with a pleasant, melting texture. I’d really like to experiment more with buttercream, maybe make it more chocolaty, or try a different flavour altogether. But, like I said, I ran out of time this month.
