Farewell to Fay - White Gold Passion Genoise
On Friday, Fay retired to a life of freedom and cruises - we can't wait to hear what Fay does next!
In the usual fashion, I made Fay a cake. She wanted me to make her something new, so I chose the White Gold Passion Genoise from Rose Levy Beranbaum's Heavenly Cakes. It consists of a genoise soaked with passionfruit syrup, filled with passionfruit curd, then topped with a white chocolate cream cheese frosting.
Before I go further, a word from our sponsor - you can now buy the BloggerAid Cook Book online here. Laws of the Kitchen has contributed a recipe, once again using passionfruit, so check it and all the other fabulous recipes out! All proceeds go to the World Food Program's School Meals Program.
Here is Fay proudly displaying her cake, even before she knew what sort it was or had tasted it. Love ya Fay!
This cake is very involved as far as steps go, so I made the genoise and the curd one night and the syrup and the frosting on the night of assembly. The genoise worked out great - I loved Rose's tips, like combining some of the batter with the melted butter before incorporating the butter into the batter; I found that this prevented an oily separated pool forming at the bottom of the bowl. I also liked her idea of sifting the flour into the batter instead of just plonking some in before folding - it helped a lot in the combination process.
Here's a peek inside the cake, showing the layers:
The sweetness of the frosting is cut by the sharpness of the passionfruit, and together it makes a wonderful combination. None was left over, even though I cut the cake into tiny pieces for it to go around as far as possible.
The recipe is as follows:
3 tablespoons clarified butter
1 teaspoon vanilla extract
1/2 cup sugar
1/2 cup cake flour
1/2 cup minus one tablespoon cornflour
Preheat your oven to 175 degrees Celsius and grease, flour and line a 9" cake pan with 2" sides.
Put the clarified butter in a heatproof bowl and warm it until almost hot, then stir in the vanilla. Cover the bowl and keep the butter warm.
In a heatproof bowl, whisk the eggs and sugar together. Put the bowl over a saucepan of simmering water and heat, stirring constantly, until lukewarm.
Remove the bowl from the heat and whisk the egg mixture with a stand mixer for 5 minutes or until the mixture has quadrupled in volume.
Whisk together 1 cup of the beaten eggs with the clarified butter mixture. Set aside.
Sift half the flour over the rest of the egg mixture and fold in with a spatula. Once it has been combined, fold in the remaining flour and finally the butter mixture.
Pour the batter into the prepared pan and bake for 20-20 minutes or until the cake is golden and has started to pull away from the sides of the pan. Unmould onto a wire rack sprayed with cooking oil immediately, then, leaving the bottom pan lining in place, turn the cake right side up and leave to cool completely.
3 egg yolks
1/2 cup sugar
1/2 cup passionfruit pulp
pinch of salt
Whisk the egg yolks, sugar and butter in a saucepan until well combined. Whisk in 5 tablespoons of passionfruit puree and the salt. Cook the mixture on medium-low heat, stirring continuously, until the mixture thickens enough to coat the back of your spoon. Remove the curd from the heat and strain into a heatproof bowl, then stir in the remaining passionfruit. Allow the curd to cool at room temperature for 30 minutes before covering and refrigerating until cool.
1 vanilla bean
3/4 cup sugar
1/2 cup plus 2 tablespoons passionfruit pulp
Put the sugar into a small saucepan, and scrape in the vanilla beans from the split vanilla bean pod, and rub them into the sugar. Add the pod to the pan, and stir in 1/2 cup passionfruit pulp. Bring the mixture to a rolling boil, stirring continuously, then cover it and remove it from the heat and allow it to cool completely. Transfer it to a jug and stir in the rest of the passionfruit pulp.
White Chocolate Frosting
100g white chocolate
2 x 50g butter
1 egg yolk
170g cream cheese
1/2 tablespoon creme fraiche or sour cream (I used natural set yoghurt)
1/4 teaspoon vanilla extract
In a baine marie, melt the white chocolate and 50g butter. Whisk in the egg and yolk, and continue whisking and heating the mixture until it reaches 60 degrees Celsius. Remove the mixture from the heat, and allow it to cool to ~20 degrees Celsius. To speed it up, you may refrigerate the mixture for around 20 minutes. (I had to - my kitchen temperature was 26 degrees Celsius!)
In a stand mixer bowl, whisk the cream cheese and 50g butter until smooth, then beat in the creme fraiche (or sour cream). Gradually beat in the white chocolate mixture and vanilla, then increase the mixer speed and beat until light and creamy.
Using a serrated knife, remove the top and bottom crusts of the cake, and cut it in half. Brush the top and bottom of each half with the syrup.
Place one half of the cake onto a cardboard cake round. Spread it with 3/4 cup passionfruit curd, and place the other half of the cake on top. Frost the top and sides of the cake with the frosting, swirling the top, and place the cake in the fridge for an hour to set the frosting. Put small dabs of the remaining passionfruit curd on top of the frosting and swirl to combine.
I recommend buying Rose's book if you are into making cakes - it is very beautiful and packed with wonderful recipes and tips.
