Mastering the Classic Vinaigrette

Forget pre-mixed bottles; a proper dressing is made in the bottom of your salad bowl in seconds. Once you grasp the chemistry of the emulsion, you can dress any leaf or vegetable with confidence.

Before you start

Salt is your anchor.

Always dissolve your salt in the acid before adding the oil. If you add oil first, the salt will simply sink to the bottom of the bowl and stay gritty.

  • Small whisk
  • Mixing bowl
  • Measuring spoons
Ingredients

What goes in.

  • 1 tbspred wine vinegar or fresh lemon juice
  • 1/2 tspfine sea salt
  • 1 tspDijon mustard
  • 3 tbspextra virgin olive oil
  • to tastefreshly cracked black pepper
The key technique

Slow and steady binding

The mustard acts as a bridge between the acid and oil. Drizzle the oil drop-by-drop at first; once the mixture begins to look creamy, you can pour in a steady, thin stream.

Step by step

The method.

  1. Season the acid

    Place the vinegar, salt, pepper, and mustard in the bowl. Whisk until the salt crystals vanish into the liquid.

  2. Add the oil

    Whisking vigorously with one hand, add the olive oil in a slow, continuous stream with the other. Stop when the dressing turns opaque and coats the back of the whisk.

  3. Adjust

    Dip a leaf into the dressing to taste. It should be sharp enough to brighten the greens but rounded out by the oil.

Variations

Other turns to take.

Shallot infusion

Mince one small shallot and let it soak in the vinegar for 10 minutes before adding the oil to soften its bite.

Herbed

Whisk in a teaspoon of finely chopped fresh parsley, chives, or tarragon after the emulsion has formed.

Tips & troubleshooting

When it doesn't go to plan.

Tip

If the dressing breaks—meaning the oil separates—whisk in a few drops of water to bring it back together.

Tip

Use a bowl larger than you think you need; it gives your wrist room to move and keeps the dressing from splashing out.

Tip

Taste the dressing with the actual greens you plan to serve, not just on a spoon, as the flavor changes when it coats the surface of a leaf.

Questions

The ones that keep coming up.

Can I make this in advance?

Yes, but it will separate in the fridge. Give it a quick whisk or shake before pouring it over your greens.

What is the best ratio?

3:1 oil-to-acid is the standard starting point. If you prefer a sharper dressing, pull back to 2:1.
