GENOISE CAKE RECIPES

Steps:

• Heat oven to 350 degrees. Butter a 10 1/2-by-15 1/2-by-1-inch jelly-roll pan. Line with parchment; butter and flour paper, tapping out the excess flour.
• Sift flour, cocoa, and baking soda together twice into a medium bowl. Set aside. In a small saucepan over low heat, melt butter. Skim off white foam, and pour clear yellow butter into a bowl, discarding white liquid at the bottom. Set aside in a warm place.
• In a medium-size heat-proof bowl, whisk together eggs and sugar. Set bowl over a pan of simmering water; stir until mixture is warm to the touch and sugar has dissolved. Remove from heat, and beat on high speed until mixture is thick and pale and has tripled in bulk. Reduce speed to medium, add vanilla, and beat 2 to 3 minutes more.
• In three additions, sift flour mixture over egg mixture, folding in gently with a spatula. While folding in last addition, dribble melted butter over batter and fold in.
• Spread batter evenly in pan, leaving behind any unincorporated butter in the bottom of the bowl. Tap pan on counter to remove air bubbles. Bake until cake springs back when touched in center, 15 to 20 minutes. Don't overbake or cake will crack. Let sit in pan on a wire rack until cool enough to handle.
• Dust surface with cocoa powder. To make rolling easier, trim edges of cake, and cover with a sheet of waxed paper and a damp dish towel. Invert onto a work surface, and peel off parchment; dust with cocoa. Starting from one long end, carefully roll up cake in towel. Wrap in plastic; refrigerate until ready to use.

Steps:

• Heat oven to 190C/170C fan/gas 5. Brush 2 x 20cm cake tins with melted butter, line the bases with baking paper, then dust well with flour tipping out any excess. Set aside.
• Put the sugar and eggs in a large heatproof bowl, then set it over a pan of barely simmering water. Whisk with an electric hand whisk for about 7 mins or until the mixture is pale and has trebled in volume. Remove from the heat, then slowly pour in the butter folding it in as you pour until it is completely mixed in.
• Gently fold the flour and a pinch of salt into the egg mixture, then pour into your prepared cake tins. Cook for 25 mins until the cake is golden and risen – a skewer pushed into the cake should come out clean. Allow the cakes to cool for a few mins in the tin, then remove and cool completely on a wire rack.
• Meanwhile, whip the cream until it just holds its shape, then set aside. Whizz about a quarter of the strawberries with 1 tbsp sugar until smooth, then fold this purée through the cream so you get a ripple effect.
• To assemble the cakes, cut each one in half horizontally. Put one sponge on a serving plate, spread a quarter of the cream mix on top, then dot a quarter of the blueberries and raspberries around the edge. Repeat this step two more times, put the last layer of cake on top (save a top half of cake for the top layer), spread the remaining cream over, then put the blueberries and raspberries around the edge and pile the strawberries in the centre. Dust with icing sugar just before you serve.
