First, I made the roasted tomato-dried chili dipping sauce on pages 112-113 of Simple Thai Food. I doubled the recipe, and added more fish sauce and lime juice to make the sauce thinner. I also stirred in about 2 teaspoons of toasted rice powder (page 182) at the end.
Then I half-filled a 4-quart saucepan with water and brought it to a boil. I stirred in 1 tablespoon sea salt to the water and added 3 pounds of jumbo shrimp. Keeping the water simmering, I cooked the shrimp until opaque, about 3 minutes. I drained them and served them with the dipping sauce. Everyone then gathered around the table and got messy.
