  4. Process the rosemary and 2 tablespoons of caster to a coarse powder. Slowly introduce the egg yolks to the creamed butter and sugar, beating constantly. Whisk the egg whites until almost stiff.
  5. Mix the melted chocolate into the butter and sugar, then carefully fold in the ground hazelnuts, drained sultanas and the flour and cocoa. Lastly, fold in the beaten egg whites, making certain there are no lumps of unincorporated whites. Scrape the mixture into the lined cake tin.
  6. Finally, scatter the reserved hazelnuts and the rosemary sugar over the surface. Bake for 40-45 minutes until lightly firm, the top slightly cracked. Remove from the oven and leave to cool before carefully removing from the tin.
