Melt the butter in a small saucepan over medium heat.
Add the pepper, Cajun seasoning and garlic. Stir and let cook for 5 minutes.
Add the remaining ingredients. Bring to a boil then reduce heat to keep warm until you are ready to serve.
For the shrimp
Melt the butter in a large saute pan over medium-high heat.
Add the Worcestershire sauce, pepper, Cajun seasoning, garlic, and shrimp. Stir and cook shrimp until pink and done, 2-3 minutes.
Serve shrimp with broth in bowls with rice, bread and lemon wedges on the side. You'll find that you might want to just add the rice to the broth and shrimp mixture, or eat everything separately while dipping the bread into the broth. Whatever works for you!
