If you can't get a fresh lobster roll along the coast of New England, this is the next best thing - packed with real lobster chunks in a creamy herb dressing overflowing from a buttery split top bun.
Use kitchen shears to cut lengthwise through the top of each lobster tail shell from the wide end to the fin.
Steam the Tails
Fill a pot with 2 inches of water and bring to a boil. Place tails in a steamer basket over the water, cover, and steam 5 to 7 minutes until shells are fully red and meat is opaque throughout.
Ice Bath
Transfer cooked tails immediately to a bowl of ice water. Cool 3 to 5 minutes until no longer warm.
Extract and Dry
Remove meat from the shells. Pat dry aggressively with paper towels. Roughly chop into bite-sized pieces.
Build the Salad
Combine lobster, celery, chives, tarragon, lemon juice, salt, and cayenne in a bowl. Toss gently. Add mayo and fold in until just coated. Cover and refrigerate at least 15 minutes.
Toast the Buns
Spread softened butter on the flat outer sides of the buns. Toast in a nonstick skillet over medium heat 1 to 2 minutes per side until deep golden brown.
Fill and Serve
Pile cold lobster salad generously into each toasted bun. Garnish with extra tarragon or chives. Serve immediately.
Notes
Store lobster salad separately from buns in an airtight container for up to 2 days. Do not assemble in advance.
Lobster salad does not freeze. Make only what you'll eat within 2 days.
For Connecticut style: skip the mayo and herbs, toss warm lobster in melted garlic herb butter, serve immediately.
