Hollandaise
A light egg-yolk sabayon takes in warm butter slowly, becoming a glossy sauce that ribbons from the whisk and can be gently rescued if it thickens or splits.

Ingredients
4 large pasteurized egg yolks, divided (3 for the sauce base; 1 for a rescue if needed)
2 tbsp water, divided (1 tbsp cold for the sabayon; reserve 1 tbsp for adjustments)
1 tbsp fresh lemon juice
3/4 cup unsalted butter, melted and warm or clarified
1/4 tsp fine salt
1 pinch cayenne pepper (optional)
Equipment
Small saucepan · Heatproof metal bowl · Balloon whisk · Measuring spoons
Warm and whisk
01. Melt butter over low heat until warm and fluid, then keep it nearby without browning it.
02. Whisk 3 yolks with 1 tbsp cold water and lemon juice; set the bowl over barely simmering water without letting it touch.
Build the sabayon
03. Whisk constantly until the yolks turn pale and airy and leave soft ribbons; lift the bowl if it feels hot.
04. Off heat, whisk in warm butter a few drops at a time until the base turns glossy and slightly thicker.
Emulsify and season
05. Pour the remaining butter in a thin stream as you whisk; stop if an oily sheen appears and whisk smooth before resuming.
06. Whisk in 1/4 tsp salt and optional cayenne; look for soft trails and a continuous ribbon that coats a spoon.
Adjust and serve
07. For a thick sauce, whisk in warm reserved water by the teaspoon. For a split sauce, start a fresh emulsion with the reserved yolk and whisk the sauce in slowly.
08. Serve promptly over eggs, fish, or asparagus; hold briefly over warm water and whisk instead of using direct heat.
