Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Gives the sauce its sharp, pungent flavour and helps hold the mixture together.
- Egg
- Thickens the sauce as it heats and gives it a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the sweetness.
- Sugar
- Softens the sharpness of the mustard and vinegar for a rounder taste.
The step that matters
Cooking over low heat with constant stirring. Egg proteins thicken the sauce as they warm, but if the mixture gets too hot or is left unstirred, the egg can scramble and turn grainy. Gentle heat and constant stirring keep it smooth.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, sugar, egg):
- Mustardthe original
- Capsicumfits about as well
