• Salt, to taste
  • 2 lobsters (about 300 gr. each)
  • 2 cups milk
  • 7 tbsp. unsalted butter
  • 1/2 cup flour
  • 1 tsp. ground nutmeg
  • Freshly ground black pepper, to taste
  • 2 shallots, finely chopped
  • 1 cup white wine (optional)
  • 12 cups heavy cream
  • 1 tbsp. finely chopped chervil (you can replace this with chopped parsley)
  • 18 tsp. cayenne
  • 12 tsp. dry mustard
  • 100 gr. Gruyère, grated
  • 50 gr mozzarella, grated



  • Bring a pot of salted water to a boil. Add lobsters; boil for 5 minutes. Drain; halve each lengthwise. Remove and crack claws. Remove meat from bodies and claws; cut into chunks. Scrape shells' insides clean; set meat and shells aside.
  • Bring milk to a boil; set aside. Melt 4 tbsp. of the butter in a pan over medium heat. Add flour and cook until golden, 1–2 minutes. Add milk while whisking; increase heat to medium; boil. Cook, stirring, until thickened, 2–3 minutes. Add nutmeg and salt and pepper; keep sauce warm.
  • Heat broiler. Heat remaining 3 tbsp. of the butter in a skillet over medium-high heat. Add shallots; cook until golden, 1–2 minutes. Add mushrooms; cook until softened, 4–5 minutes. Add wine; cook until reduced by two-thirds, 4–5 minutes. Whisk in cream, chervil, cayenne, and reserved sauce. Reduce heat to medium-low; cook until thickened, 3–4 minutes. Add lobster; stir in mustard and 34 cup cheese. Divide half of lobster sauce between shells; sprinkle remaining cheese over top. Broil lobster halves on a baking sheet until bubbly, 2–3 minutes. Serve with remaining sauce.
