Clementine flourless cake

A couple of weeks ago, my cousin cooked the yummiest clementine cake eva. I found the receipe today and may I recommend it to you? :-)

375g clementines (about 4-5)
6 eggs
225g sugar
250g ground almonds
1 heaped teaspoon of baking powder

1 - put clementines in a pan with cold water and bring to boil. Cook for 2 hours. Drain and let cool slightly. Cut clementines in half and take out the seeds. Puree them with skin.
2 - Preheat oven to 190C (375F)
3 - Whisk eggs. Add sugar, almonds and baking powder and mix well. Add in the clementine puree and mix.
4 - Pour into a 21cm buttered and floured cake pan and bake (on the middle rack) for approx 40 mins. Then cover with foil and bake for another 20 mins.

Then cut yourself a piece and enjoy!
Yum!
Btw, this seems to be a recipe by Nigella Lawson and seems to be very famous. Just try searching for it!
