METHOD :-
Beat the yoghurt, orange rind, and castor sugar in a bowl until smooth.
Stir in the sieved self-raising flour, beaten eggs, and vegetable oil, until mixture is smooth and lump free.
Fill a 10" cake tin (or two 7" tins) with the mixture and level off the top.
Bake at Gas Mark 5 / 375°F / 190°C (170°C for fan oven) for 25 - 30 minutes, until golden brown, and springy to the touch.
Allow to cool slightly before turning the sponge out of the tin.
Whip the double cream until it holds its shape.
Add the half jar of lemon curd, and stir thoroughly.
Spread the lemon cream topping evenly over the sponge.
Decorate with the segments of two oranges.
