I quite enjoyed Jamie Oliver's TV series travelling to different cities. In Athens he whipped us this cake and I recreated it with success using homemade yoghurt.
5 eggs
225g yoghurt
225g caster sugar
75g ground almonds
zest of lemon and orange
150g plain flour
200g polenta or semolina
2 tsp baking powder
200ml olive oil

Syrup:
100ml honey
juice of lemon and orange
150g toasted, chopped pistachios

Mix all the ingreds and pour into 20-22cm cake tin greased and floured. Bake at 180 C for 30-35 mins.

Make syrup. Pour the cold syrup over a hot sponge cake pricked all over with a toothpick or wait till the cake cools completely (1hr) and pour hot syrup over it.
