Hollandaise is a delicious sauce made by emulsifying butter, egg yolk, and an acid, usually lemon juice. It goes great with fish, vegetables or with toast and eggs. Watch Chef Gabe prepare all these dishes and more.
Whisk butter with egg yolks in a heatproof bowl over a medium sauce pan with a half inch of barely simmering water.
Slowly add boiling water and continue to whisk for seven to 10 minutes until it thickens.
Take off the heat and stir in lemon juice, cayenne, and salt to taste. Leave the bowl over the water to keep it warm; whisk occasionally.
