How to Emulsify a Vinaigrette
A vinaigrette that separates immediately is a frustration, but a stable emulsion turns into a clinging, cohesive sauce. It is not about the speed of your whisking, but the patience with which you incorporate the fat.
Consistency is a matter of pacing.
The secret lies in the 'slow drip.' If you pour the oil too quickly, the liquid will break before it ever forms a bond.

What goes in.
- 1 tbspDijon mustard
- 2 tbspacid (red wine vinegar, lemon juice, or sherry vinegar)
- 6 tbspneutral oil or extra virgin olive oil
- to tastekosher salt and black pepper
Stabilizing the Suspension
Add your oil in drops at first, not a stream. Wait until the initial droplets disappear into the mustard and vinegar base before adding more.
The method.
Combine the base
Whisk the vinegar, Dijon mustard, salt, and pepper in your bowl until the salt dissolves and the mixture looks uniform.
Incorporate the oil
While whisking constantly, add the oil drop by drop. Continue until about one-third of the oil is integrated and the mixture starts to look slightly opaque.
Finish the stream
Once the emulsion is established, pour the remaining oil in a thin, steady stream. Keep whisking until the dressing is thick and pale.
Test for stability
Let the bowl sit for a minute. If the oil beads on top, whisk again with a teaspoon of water to tighten the bond.
Other turns to take.
The Jar Method
Place all ingredients in a mason jar, seal it tight, and shake vigorously for 30 seconds; the friction creates the emulsion without a whisk.
Shallot Infusion
Macerate finely minced shallots in the vinegar for 10 minutes before starting the emulsion to build deeper complexity.
When it doesn't go to plan.
Always use a bowl that allows the whisk to reach the bottom edges.
A room-temperature mustard emulsifies more readily than one taken straight from the refrigerator.
If the dressing breaks, do not discard it; put a fresh teaspoon of mustard in a clean bowl and whisk the broken dressing into it slowly, as if adding oil.
The ones that keep coming up.
Why does my vinaigrette keep separating?
Usually, the oil was added too quickly, preventing the mustard from coating the fat droplets. Slow down the pour.
Can I use a blender?
Yes, a blender is the most efficient tool for large batches. Pulse the base first, then drizzle the oil through the lid's opening while the motor runs.
