Instructions

  1. Place the frozen shrimp in a colander in the sink, and run hot water over them while stirring occasionally until they separate and begin to thaw, about 1 minute.
  2. Set aside to drain for another 5 minutes or so until they're thawed yet still chilled in the middles, then place them in a large bowl.
  3. To the bowl add the sherry, lime juice, seasoning salt, black pepper, ancho powder, and 1/2 teaspoon cocktail sauce, and stir well to coat; set aside for another 10 minutes or so, stirring occasionally.
  4. (You can put them in a container in the fridge for later, if need be, or into a container for taking to a picnic or potluck.).
  5. Serve with your favorite cocktail sauce for dipping.
  6. Note: you can, of course, use the marinade on thawed cooked shrimp - just toss them well in the marinade and let sit for at least 10 minutes.
