Gâteau de Marrons de l’Ardèche

In Le Trésor de la cuisine du bassin méditerranéen Prosper Montagné revised and prefaced a collection of recipes from seventy French doctors. Enlivened by many small woodcuts and one gruesome advertisement for the digestive medicines of Dr Zizine, the recipes are interesting. This is Dr Cleu’s recipe which I have adapted only slightly.
