Mastering Emulsified Sauces
Emulsions are the difference between a thin juice and a luxurious sauce. Whether you are building a Hollandaise or a classic vinaigrette, the chemistry remains the same: steady patience and the right level of agitation.
Temperature is your greatest ally
Keep your bowl stable with a damp towel underneath. If your sauce breaks—meaning the fat separates—don't throw it out; start a new yolk in a clean bowl and slowly whisk the broken sauce into it.

The Golden Drop Method
The first quarter of your fat must be added drop by drop. If you pour too fast early on, you prevent the yolk from forming the initial matrix required to hold the rest of the fat.
The method.
Prepare the base
Whisk the egg yolks and acid in your bowl until they lighten in color and increase in volume.
Establish the bond
Place the bowl over a pot of barely simmering water. Whisk continuously, adding the fat one drop at a time until the mixture thickens and coats the back of a spoon.
The steady stream
Once the foundation is set and thick, you can increase the fat addition to a thin, steady stream. Keep whisking at a constant pace to maintain the structure.
Finish and season
Remove from heat once the desired thickness is reached. Taste and add salt immediately.
Other turns to take.
Béarnaise
Replace the lemon juice with a reduction of shallots, tarragon, and vinegar.
Vinaigrette
Use mustard as your emulsifier, whisking oil into vinegar and aromatics at room temperature.
When it doesn't go to plan.
Use a damp kitchen towel folded into a ring to stabilize your bowl on the counter.
If the sauce gets too thick, whisk in a teaspoon of warm water to loosen it.
Never let the bottom of your bowl touch the water; the steam does the work.
The ones that keep coming up.
Why did my sauce curdle?
The heat was likely too high and the eggs scrambled, or you added the fat faster than the yolks could absorb it.
Can I use cold butter?
No, the fat must be liquid to incorporate smoothly into the yolks.
