Mastering the Classic Vinaigrette
Knowing how to balance fat and acidity allows you to dress greens or roasted vegetables without relying on bottled shortcuts. Once you understand the mechanics of the emulsion, you can swap vinegars, oils, and aromatics to suit whatever is in your pantry.
The emulsion is physical, not chemical
You are forcing oil and vinegar to stay together temporarily. If you skip the slow-pour or the whisking, the dressing will break back into two layers within minutes.
- Small stainless steel bowl
- Balloon whisk
- Measuring spoons
What goes in.
- 1 tbspred wine vinegar or fresh lemon juice
- 1/4 tspfine sea salt
- 1/2 tspDijon mustard
- 3 tbspextra virgin olive oil or neutral grapeseed oil
- to tastefreshly cracked black pepper
Slow and steady stream
The mustard acts as a bridge between the acid and oil, but only if you add the oil drop by drop at first. Once the mixture turns opaque and starts to thicken, you can pour the remaining oil in a thin, constant stream while whisking constantly.
The method.
Dissolve the salt
Whisk the salt and vinegar together in the bowl until the salt grains disappear completely.
Add the stabilizer
Whisk in the mustard until fully incorporated.
Stream the fat
Add the oil in a very slow trickle while whisking steadily. Continue until the vinaigrette appears creamy and thick.
Season
Taste with a leaf of lettuce. Add black pepper or more salt if the acidity feels too sharp against the oil.
Other turns to take.
Shallot-Forward
Mince one small shallot very finely and let it sit in the vinegar for 10 minutes before adding the oil.
Herbed
Add one teaspoon of finely minced fresh chives, parsley, or tarragon after the emulsion is set.
When it doesn't go to plan.
Always dress your salad at the table. Salt draws water out of greens, so if you mix it in too early, the leaves will wilt.
If the dressing breaks, add a half-teaspoon of warm water and whisk vigorously; it will pull back together.
Use neutral oils like grapeseed when you want the brightness of the vinegar to shine, and olive oil when you want a rich, grassy finish.
The ones that keep coming up.
Can I make this in a jar?
You can, but it won't be as stable. Shake the jar violently until the contents look pale and cloudy, but note that it will separate much faster than a whisked dressing.
