Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolk
Emulsifies the oil and vinegar, so the sauce thickens into a smooth, stable emulsion.
Salad oil
Forms the body of the sauce, giving richness and a creamy texture when emulsified.
Tarragon vinegar
Adds acidity that sharpens the flavour and balances the richness of the oil.
Made mustard
Adds sharp flavour and helps stabilise the emulsion.

The step that matters

Gradually work in the salad oil. Adding the oil slowly, a little at a time, lets the egg yolk coat each droplet and form a stable emulsion. Adding it too fast can cause the sauce to split and turn oily.

Swap the parsley
