Specifically, the authors write: “We were inspired by kestane çorbasi, a pureed chestnut soup that can lean sweet or savory depending on who is at the stovetop. Along with the woodsy, rich chestnuts, our soup achieves an appealing sweet-savory balance from shallots and mushrooms (both classic ingredients). The addition of baharat in our version, which we saw in some ­recipes, manages to augment all the distinct flavors in the soup with its ­complex spice.”
