Gateau au chocolat de metz
A rich but light chocolate cake with a fudgy centre. The texture is achieved by using potato flour, which can be bought online from Ocado.

To drink: Alsace's sweetest most expensive wine style, Sélection des Grains Nobles, would go well with this but fortified Australian Muscat is good with chocolate:Campbells Rutherglen Muscat, £10.50-£11.55, Waitrose and Adnams Cellar & Kitchen.
