Hollandaise Sauce

The mother sauce that terrifies home cooks more than it should. Hollandaise is an emulsion: egg yolks, clarified butter, lemon, and cayenne, whisked together over gentle heat. The only skill involved is patience — add the butter slowly and keep the heat low. If it breaks, whisk in a tablespoon of cold water. It almost always comes back.

Prep: 5 min Cook: 10 min Total: 15 min Serves: 4

Instructions

  1. Whisk egg yolks, lemon juice, and cold water in a heatproof bowl until slightly thickened and lighter in color.

  2. Set the bowl over a pot of barely simmering water. The bottom of the bowl must not touch the water.

  3. Whisk continuously while adding the melted butter in a very thin stream — start drop by drop, then increase to a steady drizzle as the emulsion builds. This should take about 3 to 4 minutes.

  4. The sauce is done when it is thick enough to coat the back of a spoon and holds a line when you draw your finger through it.

  5. Season with salt and cayenne. If the sauce is too thick, whisk in a few drops of warm water. If it breaks, whisk in 1 tablespoon of ice water — this usually rescues it.

  6. Serve immediately. Hollandaise does not reheat well. If you must hold it, keep the bowl over warm (not simmering) water for up to 30 minutes.
