Mastering the Vinaigrette Emulsion
The difference between a broken, oily mess and a cohesive vinaigrette is the rate at which you introduce the oil. Once you master the mechanics of the emulsion, you stop following recipes and start building dressings based on what is in your pantry.
Temperature and patience matter more than the ingredients.
Use a room-temperature bowl and whisk. If you dump the oil in too quickly, the liquid will separate instantly; take your time with the initial droplets.

What goes in.
- 1 tbspDijon mustard (the primary stabilizer)
- 2 tbspred wine vinegar or fresh lemon juice
- 1/2 tspfine sea salt
- 6 tbspextra virgin olive oil
The Slow Stream
The first two tablespoons of oil are the most critical. Whisk them in slowly until the mixture turns opaque and thick before pouring the remaining oil in a thin, steady thread.
The method.
Prepare the base
Whisk the mustard, vinegar, and salt in your bowl until the salt granules disappear and the mustard is fully dissolved.
Begin the drop-by-drop
Add the oil in tiny droplets while whisking constantly. You are looking for the mixture to begin thickening and turning pale.
Finish the stream
Once the initial drop-by-drop emulsion is stable, pour the rest of the oil in a thin, constant stream. Keep whisking until the texture is creamy and uniform.
Check the stability
Dip a leaf of lettuce into the bowl. If the dressing coats the leaf without sliding off immediately, it is ready.
Other turns to take.
Shallot Infusion
Mince one small shallot and let it sit in the vinegar for 10 minutes before adding the mustard and oil.
Honey Balanced
Whisk in 1 teaspoon of honey with the mustard to temper sharp vinegar.
When it doesn't go to plan.
If your emulsion breaks, put a teaspoon of fresh mustard in a clean bowl and slowly whisk the broken mixture into the new mustard.
Add herbs like chives or parsley only after the emulsion is fully formed to prevent them from bruising during the heavy whisking.
The acid content determines how much oil you can hold; if the dressing tastes too sharp, whisk in another tablespoon of oil.
The ones that keep coming up.
Why does my dressing separate in the fridge?
The oil solidifies at colder temperatures. Let the dressing sit on the counter for ten minutes and give it a quick whisk to bring it back together.
Can I use a blender?
Yes, but use a high-speed blender only for large batches. For a standard salad, a hand whisk provides better control over the texture.
