Spicy Pumpkin Chipotle Soup

Heat a substantial saucepan over an intermediate temperature setting, stirring the butter until it is fully incorporated and melted. Introduce the flour into the mixture; continue cooking until it reaches a light golden color, approximately 3 minutes. Combine the vegetable stock with the flour mixture and raise the heat to its highest level, stirring constantly until it reaches a rolling boil. Gradually incorporate the pumpkin puree into the mixture, ensuring there are no lumps remaining; then add the half-and-half, chipotle peppers, sofrito, Worcestershire sauce, salt, and paprika. Continue to cook the mixture over a low heat setting until it thickens and reaches a suitable temperature, approximately 8 minutes.
