Queen Mothers Cake
I found with little time to go that I needed a marble work surface – just like that, produce a marble work surface; what, you don’t have one? – and what’s more, compound chocolate (which I thought was the stuff bulk Easter eggs are made from, and to be avoided). Tempering chocolate makes me think of frightening episodes of Masterchef, which might be a good enough reason to give it a go one day, marble benchtops or not, but suffice to say I wasn’t up for it this early in the morning.
I ran around looking at leaves from plastic plants, figuring they probably weren’t toxic, melted uncompound chocolate in 20-second bursts in the microwave (not having a dedicated double-boiler either) and hastily slathered the backs of the leaves with it and laid them on a plate. Into the fridge for about 20 minutes with them, then the leaves peeled away from the chocolate, my fingers melting it upon contact so that I had to prefreeze them uncomfortably with ice water.
It seemed to work. They looked like leaves. And no one was poisoned, so win-win.
FOR THE CAKE:
1 ½ c. almonds, skinned
6 oz. semisweet chocolate, chopped
¾ c. sugar
6 oz. unsalted butter
6 large eggs, separated
1/8 tsp. salt
1 tsp. fresh lemon juice
FOR THE ICING:
½ cup heavy cream
2 tsp. instant espresso or coffee powder
8 oz. semisweet chocolate, chopped
To make the cake, toast the almonds in a single layer in a shallow pan in a 350 oven for 12 to 15 minutes, shaking the pan a few times, until the almonds are lightly colored and give off a delicious smell of toasted almond when you open the door. Set aside to cool.
Adjust a rack one-third up in the oven and preheat oven to 375. Butter the bottom and sides of a 9'' x 3'' springform pan and line the bottom with a round of parchment paper cut to fit. Butter the paper. Dust the pan all over with fine, dry breadcrumbs, invert over paper, and tap lightly to shake out excess. Set the prepared pan aside.
Place the chocolate in the top of a small double boiler over warm water on moderate heat. Cover until partially melted, then uncover and stir until just melted and smooth. Remove the top of the double boiler and set aside until tepid or room temperature. Place the almonds and ¼ cup of the sugar (reserve remaining ½ cup sugar) in a food processor fitted with a metal chopping blade. Process very well until the nuts are fine and powdery. Stop the machine once or twice, scrape down the sides, and continue to process. Process for at least a full minute. I have recently realized that the finer the nuts are, the better the cake will be. Set aside the ground nuts.
In the large bowl of an electric mixer beat the butter until soft. Add ¼ cup of the sugar (reserve the remaining ¼ cup sugar) and beat to mix. Add the egg yolks, one at a time, beating and scraping the sides of the bowl as necessary until smooth. On low speed add the chocolate and beat until mixed. Then add the processed almonds and beat, scraping the bowl, until incorporated.
Now, the whites should be beaten in the large bowl of the mixer. If you don't have an additional large bowl for the mixer, transfer the chocolate mixture to any other large bowl. Wash the bowl and beaters.
In the clean bowl of the mixer, with clean beaters, beat the egg whites with the salt and lemon juice, starting on low speed and increasing it gradually. When the whites barely hold a soft shape, reduce the speed a bit and gradually add the remaining ¼ cup sugar. Then, on high speed, continue to beat until the whites hold a straight point when the beaters are slowly raised. Do not overbeat.
Stir a large spoonful of the whites into the chocolate mixture to soften it a bit. Then, in three additions, fold in the remaining whites. Do not fold thoroughly until the last addition and do not handle more than necessary.
Turn the mixture into the prepared pan. Rotate the pan briskly in order to level the batter.
Bake for 20 minutes at 375 and then reduce temperature to 350 and continue to bake for an additional 50 minutes (total baking time is 1 hour and 10 minutes). Do not overbake; the cake should remain soft and moist in the center. (The top might crack a bit; it's okay.)
Wet and slightly wring out a folded towel and place it on a smooth surface. Remove the cake pan from the oven and place it on the wet towel. Let stand until tepid, 50 to 60 minutes.
Release and remove the sides of the pan (do not cut around the sides with a knife—it will make the rim of the cake messy). Now, let the cake stand until it is completely cool, or longer if you wish.
The cake will sink a little in the middle; the sides will be a little higher. Use a long, thin, sharp knife and level the top. Brush away loose crumbs.
Place a rack or a small board over the cake and carefully invert. Remove the bottom of the pan and the paper lining.
The cake is now upside down; this is the way it will be iced. Place 4 strips of parchment paper (each about 3'' x 12'') around the edges of a cake plate. With a large, wide spatula, carefully transfer the cake to the plate; check to be sure that the cake is touching the paper all around (in order to keep the icing off the plate when you ice the cake). If you have a cake-decorating turntable or a lazy Susan, place the cake plate on it.
To make the icing, scald the cream in a 5- to 6-cup saucepan over medium heat until it begins to form small bubbles around the edges or a thin skin on top. Add the espresso or coffee powder and whisk to dissolve. Add the chocolate and stir occasionally over heat for 1 minute. Then, remove the pan from heat and whisk or stir until the chocolate is all melted and the mixture is smooth.
Let icing stand at room temperature, stirring occasionally, for about 15 minutes or a little longer, until icing barely begins to thicken.
Then, stir to mix, and pour it slowly over the top of the cake, pouring it onto the middle. Use a long, narrow metal spatula to smooth the top and spread the icing so that a little of it runs down the sides (not too much—the icing on the sides should be a much thinner layer than on the top). With a small, narrow metal spatula, smooth the sides.
