In a large stockpot, melt the butter over medium heat. Slowly stir in the flour to make a roux, and cook for about 3 minutes, stirring frequently.
Add in the onion, celery, garlic, salt, and white pepper. Stir and cook for about 4 minutes.
Add the sherry, Worcestershire, broth, tomato paste, and hot sauce, and then gradually whisk in the cream so that no lumps form.
Bring to a simmer, cover, and let cook for about 30 minutes, until soup has reduced by 1/3.
Stir in 3/4 of the crab meat and all of the roe and simmer for another 10 minutes.
Remove the pan from the heat and season with salt and black pepper to taste.
Ladle soup into bowls, and top off with the remaining crab meat and a sprinkle of fresh chives and paprika.
Serve with crusty french bread.
