Here's the Nigella Clementine cake
4-5 clementines (about 375g)
6 eggs
225g sugar
1 heaped teaspoon baking powder
Put the clementines in a pan with some cold water, bring to the boil and cook for 2 hours. Drain, and, when cool, cut each clementine in half and remove the pips. Then pulp everying-skins, pith, fruitin the processor. Preheat over to gas mark 5( 190 degrees). Butter and line a 21 cm Springform tin.
Beat the eggs. Add the sugar, almonds and baking powder. Mix well, adding pulped clementines.
Put in tin and bake for an hour, when a skewer will come out clean, covering with foil for last 40 minutes to prevent top burning, if necessary.
[Note--last time I baked this it took more like an hour and ten minutes. Perhaps the oranges were juicier).
It keeps brilliantly for days after you make it. In fact, it's better to leave it for a day before you serve.
