Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare
In a saucepan, beat the eggs.
Add the milk and beat again.
Stir in the vinegar and water, mixing well to prevent curdling.
In a separate bowl, combine the dry ingredients: sugar, salt, mustard, and cornstarch.
Cook
Gradually add the dry mixture to the egg mixture over low heat, stirring constantly until thickened.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main structure and thickening power as they set with heat.
- Cornstarch
- Thickens the dressing as it heats, giving it a smooth, body-rich texture.
- Vinegar
- Adds acidity that gives the dressing its tangy, sharp flavour.
- Sugar
- Balances the acidity and sharpness of the vinegar with sweetness.
The step that matters
Gradually add the dry mixture over low heat. Adding the dry mix slowly and stirring constantly keeps the cornstarch dispersed and prevents lumps. Low heat keeps the egg proteins from scrambling while the starch thickens the dressing evenly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, milk, vinegar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Sweet potatofits about as well
Fit is the average pairing score against sugar, egg, milk, vinegar. Candidates are from the same food group and used in at least 100 recipes.
