This recipe comes to us from Kaye Worthington. It is from an Australian magazine called The Australian Womens Weekly. When making them, you must remember that Australians use metric measurements e.g. 1 cup = 250 ml, etc. Also, with sponge cakes, eggs should be at room temperature, not straight from the fridge.
½ cup castor sugar
1 cup corn flour
Lightly grease a deep 23 cm round cake pan. Beat eggs in a bowl with electric mixer for about 7 minutes or until thick and creamy. Gradually add sugar, beating well after each addition. Sift corn flour three times, then sift corn flour over egg mixture. Gently fold flour into egg mixture. Spread mixture evenly into prepared pan, bake in moderate oven (180c) for about 40 minutes or until cooked when tested.
Turn sponge onto a wire rack to cool. Split cold cake in half, spread halves with cream, jam, or icing. I prefer to spread raspberry jam on the bottom half and then either spread icing or cream and top with strawberries on the top half.
