Edmonds Fielder’s Classic Sponge (Recipe Courtesy of Edmonds Cookery Book)
- Set oven to 190°C.
- Beat egg whites and salt until stiff. Add sugar gradually and beat until stiff and sugar has dissolved.
- Add egg yolks and vanilla essence. Beat until well blended and ribbon trail forms when beaters are lifted.
- Sift cornflour, flour and baking powder together 3 times. Fold gently into egg mixture with a metal spoon.
- Pour into two greased and lined 20cm sandwich tins. Bake for 15 - 20 minutes or until cake springs back when lightly touched.
- Leave in tin for 10 minutes before turning out onto a cooling rack.
Raspberry Mousse Filling
- Heat the raspberries and sugar in a small saucepan. Stir until all of the raspberries break down and are heated through.
- Pour the raspberry mixture through a strainer and into a new saucepan.
- Add the gelatine to the strained raspberry mixture and stir over heat until the gelatine is just dissolved. Remove from the heat and set aside.
- Whip the cream until it forms soft peaks. Fold the cooled raspberry mixture into the whipped cream.
Whipped White Chocolate Buttercream Frosting (Makes about 2½ cups of frosting)
