Fiber-rich and high in vitamin C, cauliflower contains anticancer compounds. It gets a nutty-sweet flavor when roasted that's turned up a notch when you preheat the pan, which deepens color and caramelization. And while maple, lemon, and clove may seem like an unusual combination, they work together to bring a unique deliciousness to this soup.
If you're planning to freeze the soup, add all the cooked florets to the soup before blending and stir in pancetta before freezing. When you reheat it, top with another crunchy element like fried shallots or toasted breadcrumbs.
