NIGELLA LAWSON HOME RECIPES

Steps:

• Put the clementines in a pot with cold water to cover, bring to the boil, and cook for 2 hours. Drain and, when cool, cut each clementine in half and remove the seeds. Then finely chop the skins, pith, and fruit in the processor (or by hand, of course).
• Preheat the oven to 375 degrees F.
• Butter and line an 8-inch springform pan with parchment paper.
• Beat the eggs. Add the sugar, almonds, and baking powder. Mix well, adding the chopped clementines. I don't like using the processor for this, and frankly, you can't balk at a little light stirring.
• Pour the cake mixture into the prepared pan and bake for 1 hour, when a skewer will come out clean; you'll probably have to cover the cake with foil after about 40 minutes to stop the top from burning. Remove from the oven and leave to cool, in the pan on a rack. When the cake is cold, you can take it out of the pan. I think this is better a day after it's made, but I don't complain about eating it anytime.
• I've also made this with an equal weight of oranges and lemons, in which case I increase the sugar to 1 1/4 cups and slightly Anglicize it, too, by adding a glaze made of confectioners' sugar mixed to a paste with lemon juice and a little water.

Steps:

• For the cake: heat oven to 350 degrees. Butter a 9-inch springform pan and line with parchment paper. In a large saucepan, combine Guinness and butter. Place over medium-low heat until butter melts, then remove from heat. Add cocoa and superfine sugar, and whisk to blend.
• In a small bowl, combine sour cream, eggs and vanilla; mix well. Add to Guinness mixture. Add flour and baking soda, and whisk again until smooth. Pour into buttered pan, and bake until risen and firm, 45 minutes to one hour. Place pan on a wire rack and cool completely in pan.
• For the topping: Using a food processor or by hand, mix confectioners' sugar to break up lumps. Add cream cheese and blend until smooth. Add heavy cream, and mix until smooth and spreadable.
• Remove cake from pan and place on a platter or cake stand. Ice top of cake only, so that it resembles a frothy pint of Guinness.
