Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins thicken the dressing as they heat, giving it a creamy body.
- Oil
- Oil forms an emulsion with the mustard mixture, adding richness and a thick texture.
- Dry mustard
- Mustard helps stabilise the emulsion and adds sharp flavour.
- Vinegar
- Vinegar adds acidity that brightens the flavour and balances the richness of the oil.
- Milk
- Milk adds moisture and mellows the dressing's texture and flavour.
The step that matters
Heating the mixture with the eggs. Stir constantly over low heat. Egg proteins set as they warm, so uneven or high heat can scramble the eggs and leave lumps, while gentle constant stirring lets the dressing thicken smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, vinegar, milk):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Sweet potatofits about as well
Fit is the average pairing score against sugar, egg, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
