Preparation
Step 1
Shrimp: Using kitchen shears and working one at a time, cut along the length of the backs of shrimp, cutting through shells and just deep enough into flesh to expose veins; remove veins.
Bring large saucepan of salted water to a boil and ad 1/4 cup Old Bay seasoning. Squeeze lemon juice into water and add lemon halves to saucepan, return water to a boil. Add shrimp, reduce heat, and simmer until cooked through, about 3 minutes. Transfer to a bowl of ice water and let it cool. Drain and pat dry.
Just before serving, whisk oil and remaining 1 Tbsp of Old Bay in a medium bowl. Add shrimp and parsley and toss to coat.
Do ahead: Shrimp can be cooked 1 day ahead. Cover and chill.
Mustard Lime Dipping Sauce:
Whisk mayonnaise, brown mustard, lime juice, honey, brown sugar, mustard powder, and Worcestershire sauce in a medium bowl, season with hot sauce and salt. Serve shrimp with dipping sauce and lime wedges.
