Pre-heat the oven to 200ºC/180ºC fan

Grease and line a 20cm round cake tin

Cream together the cheese, butter and vanilla in a large bowl until well combined. In a separate large bowl, whisk the egg whites with 1 tbsp sugar until stiff peaks form. In a third bowl, whisk the egg yolks with all the remaining caster sugar until the mixture is thick and creamy. Add this to the cheese mixture, add the lemon rind and stir to combine. Now, gently fold in the egg whites, then the cornflour, semolina and raisins, taking care not to knock the air out of the mixture.

Transfer the mixture to the prepared tin and bake for 1 hour or until set and golden brown.

Leave to cool in the tin, dust with icing sugar and serve in slices.
