  1. Finely zest one lemon with a Microplane, avoiding the bitter white pith.
  2. Juice the 2 lemons and strain out the pulp and seeds.
  3. Put the lemon juice, water and zest in a saucepan and reduce by half over high heat.
  4. Turn the heat to the lowest setting and whisk in the cold butter cubes, whisking constantly.
  5. Keep the sauce below 60°C (140°F) so it doesn't break.
  6. Whisk in the crème fraîche to stabilize the sauce.
  7. Stir in the chopped parsley, season with flaky salt and serve right away with fish.
