Cheese: Crottin de Chavignol
This cheese has a white rind which darkens to blue-gray and eventually black with aging. Flavors of spices and nuts increase with maturity as the texture becomes dry and chalky. Don't take the name literally (in French crottin means "horse-droppings.") because it just refers to the shape and color of the mature version.
Wine: red or white Sancerre
