Curried Cauliflower Soup with Coconut and Chiles

Preheat the oven to 400 °. In a medium baking dish, toss the cauliflower florets with 1/2 tablespoon of the olive oil. Season with salt and black pepper and roast on the top shelf of the oven for about 20 minutes, until tender but not browned. Meanwhile, in a small skillet, combine the cumin, coriander and fennel seeds and toast over moderate heat, shaking the pan, until fragrant, about 2 minutes. Transfer to a spice grinder and let cool. Add the turmeric, cinnamon, allspice and cayenne and pulse until finely ground. In a large pot, heat the remaining 1 1/2 tablespoons of olive oil. Add the onion and cook over moderate heat, stirring, until softened, about 5 minutes. Add the ginger, garlic and spice blend and cook, stirring, for 1 minute. Add the wine and cook until evaporated, about 2 minutes. Add the chopped cauliflower, potato and stock and bring to a boil. Simmer over moderate heat until the vegetables are very tender, about 20 minutes. Working in batches, puree the soup in a blender until smooth and silky. Return the soup to the pot and add the coconut milk. Season with salt and pepper and simmer for about 5 minutes. Ladle the soup into bowls and pass the roasted cauliflower florets, cilantro, jalapeño and lime wedges at the table.
