Step 1

Place shrimp in a saucepan. Add water, Old Bay, and vinegar.

Step 2

Place over medium-high heat. Stir frequently. When shrimp have turned completely white, they are done. You may see 1 or 2 start to float. This is a sign that they are done. The water may not come to a boil. Do not worry about this. You do not want the shrimp to overcook. If you are unsure, pick one up and gently squeeze it. It should feel firm.

Step 3

Run cold water over shrimp to stop cooking. Let cool and then peel shrimp.

Step 4

If shrimp are on the larger side, cut them in half or thirds.

Step 5

In a medium bowl, stir together mayonnaise, lemon juice, onion, celery, and Old Bay.

Step 6

Add shrimp and mix them in. Sprinkle dill on top.

Step 7

If desired, Sprinkle a little more Old Bay on top. Serve immediately or refrigerate.
