Even though I love shrimp I hated shrimp cocktail until a friend from work brought this for us! Shrimp cocktail kicked up a notch. There's six hours (not incl in prep time) of refrigeration time, so plan ahead!
Bring water to a boil, add salt and shrimp (leave tails on). Boil for 3-4 mins or until pink, do not overcook. Strain shrimp out of the water (reserve the water). Shock the shrimp in icy cold water, to stop the cooking process. Remove the tails.
Run water (the one you boiled the shrimp in) through a strainer to strain the grits.
Put warm water and entire bottle of ketchup in a glass container, and whisk until well blended. To this sauce add in the onion, tomato, cilantro, lime juice, and hot sauce. Stir. Last but not least add the shrimp.
Seal the container and allow it to sit in the fridge for 6hrs-overnight. The longer the better. Serve with the avocados and crackers and enjoy!
