Onion soup is a classic example of caramelization as a flavour enhancer. This soup gets an added flavor boost from the garnish--a slice of gorgonzola topped bread. Cook onions and garlic in a large, heavy, covered soup pot over moderate heat until they release their moisture, about 10 minutes. Add butter and cook uncovered, until onions are a rich golden brown, about 15 minutes. Add flour and thyme and cook 5 minutes longer, stirring constantly. Add stock and tomato paste. Simmer for 15 minutes. Season with salt and pepper. Place a 0.5-ounce slice of Gorgonzola on each piece of toast and run under the broiler for 1 minute, or until the cheese is bubbly. Ladle soup into warmed bowls and float a gorgonzola toast on top of each.
