Melt the butter in a large saucepan over low heat. Add the grated celery and onion and cook them until they are translucent. Add the flour and stir until the mixture becomes a smooth paste. Cook the paste for 2 to 3 minutes; then add the chicken stock, stirring until smooth.
Raise the heat slightly, and bring the soup to a boil, and add the peanut butter, stirring to make sure that it is well mixed in. Lower the heat and allow the soup to simmer for 15 minutes. Finally add the milk, cream, hot pepper sauce, salt, and pepper, and bring the soup to the boil again. Correct the seasonings and serve hot, garnishing each serving with a few roasted peanuts.
