Savory Potato Broth
This versatile soup base is not really a broth, in the way my turkey broth is—that is, a clear liquid strained of all the ingredients that gave it flavor. In truth, the base starts cooking with several pounds of potatoes, carrots, and celery, and they stay in there. Yet, remarkably, it ends up light, clear, and clean-tasting, like a broth. To enjoy the clarity and consistency of the base, often I’ll add nothing more than rice, for texture and flavor. Onion and poached garlic make a flavorful yet light cream soup. On the other hand, I might fill the base with lots of textured ingredients, like mushrooms and barley, or lentils and ditalini pasta. And vegetables that break down during cooking and melt away, such as parsnip or winter squash and chestnut, utterly transform the texture.
