Fill large pot with water. Add celery, onion, salt and peppercorns. Bring to a boil.
Add shrimp to boiling water and cook 2-3 or until pink. Drain in colander. Put ice over shrimp to stop the cooking process. Allow to cool.
In large bowl, combine Clamato juice, ketchup, cucumber, tomato, onion, jalapeno, hot sauce, cilantro, avocado and juice of half of the lime.
Once shrimp have cooled, remove & discard the cooked celery, onion and peppercorns. Set aside a few of the whole shrimp for serving. Chop remaining shrimp into ½ inch pieces. Add chopped shrimp to the sauce and stir.
Season with salt, pepper and more hot sauce to taste.
Divide into individual dishes. Top each dish with a whole shrimp. Serve with crackers and tortilla chips.
Enjoy!
