  • Combine 2 cups water, lemon slices, 2 tablespoons brine, and 2 teaspoons coarse salt in a medium pot; bring to a boil. Add shrimp and return to a boil, then immediately remove from heat.

  • Halve shrimp lengthwise and toss with pickles, remaining 3 tablespoons brine, oil, radishes, and celery in a large bowl.

  • Stir garlic into mayonnaise, then spread on bread slices. Top with shrimp salad. Sprinkle with flaky salt and dill; serve.
