5 eggs at room temperature
200g caster sugar
half a teaspoon of salt
finely grated zest of 1 lemon
200g ground almonds
30g plain flour
Knob of butter for greasing your tin
In the other bowl, beat the whites until they form stiff peaks. If you are using the same mixer for both yolks and whites, make sure that you clean the blades well before whipping up the whites – see comment above about grease and egg whites. Add the remaining sugar to the whites gradually, and keep beating until stiff and shiny.
Using a metal spoon add two big spoonfuls of the whites to the batter to loosen it then fold in the rest, using a cutting motion to avoid knocking out all the air you’ve carefully beaten into the whites. Weigh out the salt, almonds and flour and mix together thoroughly, then fold gently into the egg mixture. There’s really no need to sift the flour/salt/almond mixture, just make sure there are no big lumps of ground almonds and that the salt is evenly distributed.
Scrape the mixture into the springform tin and bake for 40 minutes. The sponge should be coming away from the sides and the middle should spring back when gently pressed.
Leave in the tin for 10 minutes, then turn out and place the right way up on a cooling rack. Once it is completely cool, remove the paper. This cake does sink slightly in the middle as the only raising agent is the egg whites.
The image is of my entry for the street party bakeoff challenge – three layers of French almond cake, sandwiched with blueberry and raspberry jam, finished with white chocolate ganache, white chocolate fingers and white chocolate buttons, and topped with fresh strawberries and blueberries. It came second…
