At last, a plava of your dreams. This one is light as a feather, moist and freezes well. To make it extra special, split and layer with lemon curd (recipe below) and drizzle with a sharp lemon icing. To make the icing, combine 200g sieved icing sugar with the juice of 1 lemon.

Method:

● Preheat the oven to 170°C and grease and flour a square or round 27cm spring-form tin.

● Place the egg yolks in a large mixing bowl. Add the caster sugar, vanilla sugar and lemon zest and beat until thick and creamy.

● In a separate bowl, whisk the egg whites until stiff peaks form. l In another bowl, sift the cake meal with the potato flour (twice if possible) and stir in the ground almonds. Fold the dry ingredients into the egg yolk mixture, with the orange and lemon juice, and then carefully fold in the egg whites.

● Pour into your prepared cake tin and bake for 1¼ hours. When cool, dust with icing sugar.
