Notes

  • Key limes are smaller, tarter and more aromatic. Ordinary (Persian) limes work but taste milder: about 4 of them give the 120 ml of juice needed.
  • The lime juice partly sets the custard on its own — the short bake finishes it safely.
  • Traditionalists insist on a graham cracker crust and no green food colouring.
