Instructions

  1. Use double boiler or like me - place a strainer/sieve over a sauce pan of water and place a bowl in the sieve.
  2. Beat yogurt, lemon juice, egg yolks well
  3. Heat over simmering water, stirring frequently, until sauce has thickened, approx 15 min (sauce will become thinner after about 10 min and then thicken again).
  4. Remove from heat and stir in salt, mustard, pepper and dill/parsley (if using).
