  3. 3Pour in the wine and cream. Bring to a boil, reduce heat and simmer for about 5 minutes until the sauce thickens slightly.
  4. 4Mix the egg yolks and brandy in a separate bowl. Add a little of the hot sauce to warm the egg mixture, then pour it back into the sauce, stirring. Add the mustard, half of the Gruyère (1/4 cup), salt and pepper. Stir until the cheese is dissolved.
  5. 5Place the lobster pieces in the pan with the sauce and stir gently. Transfer to heatproof shells or molds, sprinkle with the remaining half of the cheese. Bake in a preheated 200°C oven for 10-15 minutes until the cheese is melted and browned. Serve hot, garnished with fresh parsley.
