I think this was from the Observer Magazine, a couple of months back.
Frosted Marmalade Cake:
Serves 8
Ingredients:
175g butter
175g golden, unrefined caster sugar
a large orange
75g orange marmalade
175g self-raising flour
for the frosting:
100g icing sugar
2 tbsps orange juice
Set the oven at 180 deg.C/Gas mark 4. Line a loaf tin about 25 x 11 x 7cm deep. Put the butter and sugar in the bowl of a food processor and beat till pale and fluffy. Finely grate the orange. Break the eggs into a small bowl and beat them lightly with a fork. With the machine at moderate speed, pour in the beaten egg, a little at a time, beating thoroughly between each addition. Beat in the marmalade and the grated orange zest.
Remove the bowl and fold in the flour with a large metal spoon. Do this slowly, firmly, but carefully, till there is no sign of any flour. Gently stir in the juice of half the orange. Spoon into the lined cake tin, lightly smoothing the top. Bake for 40 minutes, checking it after 35 with a metal skewer. Leave to cool in the tin, then remove and cool on a wire rack.
Sieve the icing sugar and mix it to a smooth, slightly runny consistency with as much of the remaining juice as it takes. Drizzle the icing over the cake, letting it run down the sides, and leave to set.
