Preparation

• Clarify butter over medium heat.
  Whisk egg yolks and lemon juice together in a stainless steel bowl. Place the bowl over top of a double boiler. Do not allow the bowl to touch the water as it will overcook the egg yolks. Slow, progressive heating is best when making hollandaise sauce.
  Whip the yolks until they reach a creamy consistency. Remove from heat.
  Slowly pour warm butter into the yolks, whipping continuously to blend. Add seasonings to taste.
  The sauce will keep, covered, in a warm place for at least 30 minutes.
