I prepare this refreshing shrimp cocktail for my family a lot during the hot summer days. Being a Mexican family, we always add Mexican hot sauce (such as Valentina® or Tapatio®) and serve with saltine crackers on the side. The trick is to start with well-chilled shrimp, ketchup, and tomato juice cocktail so it can be ready after only chilling 1 hour in the fridge. Top with additional hot sauce and avocado slices if desired. Enjoy!
