Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coleman's mustard
- Provides the main mustard flavour and pungency of the condiment.
- Egg yolks
- Thicken the mixture as they cook, giving it a smooth, creamy body.
- Sugar
- Balances the sharpness of the vinegar and mustard with sweetness.
- Boiling vinegar
- Adds acidity that sharpens flavour and helps keep the condiment tangy.
The step that matters
Cook over low heat, stirring constantly. Egg yolks thicken gently, but if they get too hot they scramble into lumps. Low heat and constant stirring keep the mixture smooth as it thickens.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, vinegar, egg, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits less well
- Cabbagefits less well
Fit is the average pairing score against sugar, vinegar, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
