Ingredients
Directions
Make the dressing
In a bowl, beat the egg yolks and add the mustard.

Finally, mix in the lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and water into a stable, thick sauce.
- Olive oil
- Provides the fat that gives the dressing its rich body and texture.
- Coleman mustard
- Helps stabilise the emulsion and adds sharp flavour.
- Tarragon vinegar
- Adds acidity and aroma that balance the richness of the oil.
- Lemon juice
- Adds brightness and acidity that balance the richness of the oil.
The step that matters
Gradually stir in the olive oil. Adding oil too quickly can overwhelm the egg yolks, so the emulsion breaks and the dressing separates instead of thickening. Adding it slowly lets the droplets be coated and dispersed evenly.
