My mom, being the Southern Lady she was, asked for the Chef at a famous New Orleans restaurant and in her sweet Southern Charm asked “what IS in this wonderful shrimp sauce”.  To which he replied:

• 1 cup Mayonnaise
• 1 cup Ketchup
• 1 Tablespoon Worcestershire Sauce
• 1 Tablespoon Lemon Juice
• 1 Teaspoon – 1 Tablespoon Horseradish (optional to make as spicy or not as you like)

Mix well – and use for shrimp dip, as a dressing for shrimp salad or even for crab legs.
