How to make a simple vinaigrette emulsion using mustard and alternative acids (yogurt, tahini)

A simple vinaigrette emulsion brightens salads, roasted vegetables, and grain bowls. This guide walks you through making stable, tangy dressings using mustard plus either vinegar or alternative acids like yogurt or tahini for creamier results. You’ll learn exact ratios, whisking technique, and how to adjust flavor and texture to taste.

  1. Step 1: Gather ingredients and tools

    Measure out 3 tablespoons of oil, 1 tablespoon of acid, 1 teaspoon mustard, a pinch of salt, and 1 teaspoon sweetener if desired. Have a small bowl or jar, a whisk or fork, and optional measuring spoons ready; consistent quantities help build a stable emulsion.

  2. Step 2: Choose your acid and flavoring

    Select white wine vinegar, apple cider vinegar, lemon juice, plain yogurt, or thinned tahini as your acid. Use vinegar or lemon for a classic vinaigrette and yogurt or tahini for creamier dressings; acid type determines brightness and mouthfeel.

  3. Step 3: Combine mustard and acid first

    Put 1 teaspoon mustard and 1 tablespoon acid into the bowl or jar and whisk or shake to blend. Mustard acts as an emulsifier and mixing it with the acid helps it disperse evenly before the oil is added, improving stability.

  4. Step 4: Slowly incorporate the oil

    While whisking vigorously, drizzle in 3 tablespoons oil very slowly, or if using a jar, add oil then screw lid and shake continuously for 30–45 seconds. Slow addition and vigorous motion create tiny oil droplets suspended in the water phase, forming an emulsion.

  5. Step 5: Adjust thickness with alternative acids

    For yogurt, thin 1 tablespoon plain yogurt with 1 teaspoon water or lemon juice before combining; for tahini, stir 1 tablespoon tahini with 1–2 teaspoons warm water to loosen. Thinning ensures easier emulsification and prevents clumping while keeping creamy texture.

  6. Step 6: Season and taste to balance

    Add 1/4 teaspoon salt, 1/8–1/2 teaspoon black pepper, and 1 teaspoon honey or maple syrup if desired. Taste and adjust: more acid for brightness, more oil for mellowness, or a pinch of salt to lift flavors; small increments avoid overcorrection.

  7. Step 7: Store or serve promptly

    Use immediately for peak emulsion, or store in a sealed jar in the refrigerator for up to 3 days, shaking well before each use. Cold storage may thicken yogurt or tahini-based dressings; allow to sit 5–10 minutes at room temperature and whisk or shake to re-emulsify.

  • Start with a 3:1 oil-to-acid ratio and adjust to taste; for creamier dressings try 2:1.
  • Use neutral oils like grapeseed, avocado, or light olive oil for balanced flavor; extra-virgin olive oil gives fruitier notes but can overpower delicate acids.
  • If the emulsion breaks, slowly whisk in 1 teaspoon hot water or add a small dollop of mustard or yogurt to rebind.
  • For garlic flavor, mince 1 small clove and let it sit with the acid for 5 minutes to mellow sharpness before whisking.
  • Make a larger batch in a jar by multiplying ingredients but keep the same ratios and shake vigorously for 60 seconds.
  • Warm walnut or sesame oil slightly (5–10 seconds microwave) to help it blend more smoothly when working with tahini.

  • Do not overheat yogurt or you will curdle it; only warm liquids slightly if needed.
  • Avoid using salty or very acidic tahini straight from the jar without thinning; it can seize and prevent emulsification.
  • If you have a mustard allergy, do not use mustard as the emulsifier; try egg yolk or aquafaba instead.
  • Consume yogurt-based dressings within 3 days and discard if they develop off smells or mold.
