Notes
Use a large pot to ensure there's enough space for all ingredients.
• Add the ingredients in stages, as each requires different cooking times.
• To enhance flavor, let the boiled crabs sit in the broth for a while after cooking.
• Serve with melted butter and lemon wedges for dipping.
• Use a tablecloth or newspaper to cover the table for easy cleanup.
