Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Provides the sharp, pungent flavour that defines the sauce.
- Egg yolk (in the method)
- Emulsifies the oil and mustard, giving the sauce a thick, smooth body.
- Olive oil
- Adds fat that carries flavour and helps form a smooth, rich texture.
- Vinegar
- Adds acidity that balances the richness of the oil and yolk.
The step that matters
Adding the yolk and oil slowly. Egg yolk and oil form an emulsion only when the oil is added gradually while stirring. Adding it too fast can cause the sauce to split and stay thin and greasy.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, olive, vinegar):
- Capsicumfits about as well
- Mustardthe original
- Cucumberfits about as well
- Tomatofits less well
Fit is the average pairing score against sugar, olive, vinegar. Candidates are from the same food group and used in at least 100 recipes.
