Step 1

Boil 2 quarts of water, seasoned with 1/2 teaspoon kosher salt. Add the shrimp and cook about 2 minutes (more or less time depending on size of shrimp), until bright pink and cooked through. Remove the shrimp with a slotted spoon and place it directly into an ice water bath to stop the cooking.

Step 2

Remove the shrimp from the ice bath with a slotted spoon. Pat the shrimp dry with a few paper towels as you place them onto the cutting board. Then chop the shrimp into bite-sized pieces.

Step 3

Finely mince the celery and thinly slice the green onions. Finely chop the chives. Stir together the chopped shrimp with the celery, green onion, chives, mayonnaise, lemon juice, Dijon mustard, Old Bay, kosher salt, and fresh ground black pepper.

Step 4

Melt the butter in a large skillet over medium heat. Place the buns cut-side down into the skillet and cook for 20 to 30 seconds until browned. Then flip and continue frying about 10 to 15 seconds on the other side.

Step 5

Place the shrimp filling into the buns and serve. Leftover filling keeps for up to 3 days in the refrigerator.
