Heat the almonds in a saucepan without fat, then melt the butter in them. Deglaze with the chicken stock and let it simmer for about 10 minutes.
Toast the almond flakes in a dry pan.
Mix the egg yolks and 1 cup of cream. Stir carefully into the no longer boiling soup. Season to taste with salt and pepper and sherry. Whip the rest of the cream until semi-stiff. Arrange the soup and serve with a spoonful of cream and almond flakes each.
