1 head cauliflower (about 2¼ pounds), cut into florets (about 6 cups)
2 tablespoons vegetable oil
1 tablespoon chopped butter
3 onions, sliced 1 inch thick
2½ teaspoons curry powder
4 cups water
2 cups chicken or vegetable broth
1 cup yogurt or labane (optional; adjust to suit tastes)
Directions
Preheat oven to 450°F . On a baking sheet, toss cauliflower with vegetable oil and 1 teaspoon salt. Spread out and roast until the florets turn brown, about 25 minutes. Set aside ½ cup of the crispiest florets for garnish.
Melt butter in a pot over medium-high heat. Add onions and cook until soft, about 5 minutes. Stir in curry powder, cauliflower, water, and broth; cover, and bring to a boil. Uncover, lower heat, and simmer 5 minutes. Using an immersion blender, blend the soup until a desired consistency is reached. Stir in yogurt or labane if using. Season with salt and pepper and serve in bowls, garnishing with the reserved cauliflower florets.
