Steps:

• Roast peppers: rub oil on peppers and put them under the broiler until blackened, turn to get all sides. Put into paper bag and seal. Let rest for 15 minutes, then peel will come right off and core and seeds will fall out. Chop peppers. Reserve one chopped pepper; set aside.
• Heat olive oil over moderate heat. Add onion and garlic and cook until soft but not brown, about 5 minutes. Stir in tomato, bell peppers (except reserved), thyme, paprika, and sugar. Cook over medium-low heat until all the tomato juices have evaporated, about 25 minutes.
• Stir in chicken stock, salt and pepper, cayenne pepper, and hot sauce (if using). Bring to boiling, lower heat, and simmer, partially covered, for 25 minutes or until vegetables are tender.
• Strain soup, reserving broth. Place solids in food processor or blender, and process until fairly smooth. Add puree back into broth.
• Melt butter and stir in the flour, cook for 1 minute. Stirring slowly, add the broth/vegetable mixture. Add reserved chopped pepper and bring to boiling. Lower heat and simmer 10 minutes.
• Ladle into bowls and add 1 tablespoon of sour cream to each bowl. For a lighter soup, this is also delicious without the sour cream.

Steps:

• Roast the peppers as directed, allow to cool in a covered bowl, then peel, seed and dice. Set aside.
• Heat the oil over medium heat in a large, heavy soup pot and add the onion. Cook, stirring often, until onion is translucent, about 3 minutes, and add the carrot and celery and a generous pinch of salt. Cook, stirring often, until the vegetables are tender and fragrant, about 5 more minutes. Stir in the garlic and cook, stirring, until fragrant, 30 seconds to a minute. Add the tomatoes with their liquid, the tomato paste, basil sprigs, cinnamon, sugar if using, and salt to taste. Cook over medium heat, stirring occasionally, until the tomatoes have cooked down slightly and smell fragrant, about 10 minutes.
• Add the diced roasted peppers, the stock or water, rice, and salt to taste. Bring to a boil, reduce the heat, cover and simmer 30 minutes, stirring from time to time. Season with freshly ground pepper, taste and adjust salt. Remove the basil sprigs.
• Using a hand blender, purée the soup, or use a blender and purée in batches, being careful to pull a dish towel down over the top and not to cover tightly with the blender lid, then return to the pot and heat through. Taste and adjust seasonings. Serve topped with croutons, Parmesan cheese, and/or slivered basil.
