Ingredients:
- 4 cold-water lobster tails (5-6 oz each / 140-170g)
- 1 lb high-quality unsalted European-style butter, cut into 1-inch cubes and chilled
- 2 tbsp dry white wine (Sauvignon Blanc) or water
- 1 tsp fresh lemon juice
- 1 sprig fresh tarragon
- 1 pinch fine sea salt
- 1 tbsp sea salt (for parboiling water)
- 2 liters water (for parboiling)
Instructions:
- Bring 2 liters of water and 1 tbsp sea salt to a rolling boil. Submerge lobster tails for exactly 2 minutes to coagulate the outer protein layer.
- Immediately transfer tails to an ice bath. Once cool, use kitchen shears to cut the top shell and carefully remove the meat in one piece.
- In a heavy-bottomed saucepan over medium-low heat, bring 2 tbsp of wine or water to a simmer.
- Reduce heat to low. Whisk in chilled butter cubes one at a time, ensuring each is emulsified before adding the next to create a Beurre Monté. Maintain a temperature between 130°F and 135°F.
- Add lemon juice, tarragon, and a pinch of salt to the butter. Gently submerge the lobster meat in the emulsion.
- Poach the lobster for 5 to 7 minutes, using a thermometer to ensure the internal temperature of the lobster reaches 135°F (57°C). Use a slotted spoon to remove and serve immediately.
