Mushroom soup, French style. Chestnuts and cepes abound in Auvergne during the autumn harvest. Filling soups of chestnuts and mushrooms fresh from the harvest became an evening staple. Warming and nutritious, these soups are rich in the earthy flavors of the land. They can also be somewhat bland. Leave it to French cooks to find ways to showcase the magnificent ingredients, in this case topping the soup with crunchy chestnuts, walnuts, cepes, and ham. The resulting soup is about as far from your grandmother’s mushroom soup as one can get.
