Mastering the Classic Vinaigrette
The secret to a sharp, balanced dressing is in the emulsification process, not the complexity of the ingredients. A stable vinaigrette bridges the gap between the sharpness of the vinegar and the weight of the oil, turning disparate components into a cohesive dish.
Control the emulsion by controlling your wrist
Ensure your mixing bowl is stable and your oil is room temperature to prevent the fats from solidifying during the whisking process.
- Small mixing bowl
- Balloon whisk
- Glass jar with lid
What goes in.
- 1 tbspRed wine or sherry vinegar
- 1/2 tspDijon mustard
- 1/4 tspFine sea salt
- 3 tbspExtra virgin olive oil
- pinchFreshly cracked black pepper
Slow-stream incorporation
Drizzle the oil into the acid base drop by drop while whisking rapidly. This mechanical action breaks the oil into microscopic droplets, suspending them in the vinegar to create a creamy consistency.
The method.
Dissolve the base
In the bottom of your bowl, combine the vinegar, salt, and mustard. Whisk until the salt has completely disappeared into the liquid.
Incorporate the oil
Begin whisking the acid mixture vigorously. With your other hand, pour the oil in a very thin, steady stream. The mixture will transition from clear to opaque and thicken as you continue to pour.
Final adjustment
Taste with a leaf of lettuce, not just your finger. The dressing should sharpen the flavor of the greens without making them taste acidic or oily.
Other turns to take.
Herb-Forward
Whisk in one teaspoon of finely minced fresh chives or tarragon after the emulsion is stable.
Citrus-Based
Swap the vinegar for fresh lemon or lime juice; use a lighter oil like grapeseed to keep the profile crisp.
When it doesn't go to plan.
Always dress your greens at the last possible second, as the acid will wilt delicate leaves if left to sit.
If the emulsion breaks—meaning the oil separates—add a drop of water and whisk hard to bring it back together.
A jar is often better than a bowl; shaking it creates a more reliable, albeit less stable, temporary emulsion.
The ones that keep coming up.
How long will this stay good in the fridge?
Use it within two days. The oils may harden in the cold, so pull it out of the refrigerator ten minutes before serving.
Does it matter what kind of mustard I use?
Yes. Dijon acts as a surfactant, meaning it helps bind the oil and vinegar together. Yellow mustard or dry powder won't provide the same stability.
