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, vinegar, and water, and beat until combined.
In a separate bowl, mix the sugar, salt, mustard, and cornstarch.
Cook the dressing
Gradually add the dry ingredients to the egg mixture while stirring to prevent curdling.
Place the saucepan over low heat and cook until thickened, stirring constantly.

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
- Thicken the dressing as they set with gentle heat and add richness.
- Cornstarch
- Thickens the liquid as it heats, giving the dressing body.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the dressing its tang.
The step that matters
Gradually add the dry ingredients to the egg mixture while stirring. Adding the dry mixture slowly and stirring constantly spreads it evenly through the eggs, so the proteins do not clump or curdle as the mixture heats. Cooking over low heat also keeps the eggs from scrambling before the cornstarch thickens the dressing.
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.
