 with Bakewell parchment paper. In a large bowl, whisk the egg whites
 and the salt until the whites are stiff. Fold in the cream of tartar
 and 1 teaspoon of sugar then whisk in the remaining sugar until the
 mixture is satiny and voluminous. Fold in the ground almonds and
 grated hazelnuts. spread the meringue mixture in 2 large discs on the
 prepared baking sheet. Bake for about 1 hour, or until the meringue
 is slightly browned. when the paper can be peeled away without
 sticking, the cakes are done. They will be slightly chewy. To make
 the butter cream, put the egg yolks in a bowl. Bring the milk to the
 boil in a saucepan and pour it on to the eggs, beating thoroughly.
 Pour the mixture into a clean pan and, stirring constantly, thicken
 the custard over low heat without allowing it to boil. Remove the pan
 from the heat and set aside to cool to tepid, beat in the butter and
 the nuts and leave to become cold. Sandwich the cakes with the butter
 cream. Sprinkle the top with icing sugar and the toasted almond
 slivers.
