Smoky Shrimp and Avocado Seviche

Most seviche recipes call for marinating raw seafood in citrus juice, but this recipe starts with cooked shrimp. An ice bath quickly cools down the boiled shrimp to prevent overcooking. You can make this appetizer earlier in the day, but don't marinate it for more than four hours, as the citrus juice will start to affect the texture of the shrimp.
