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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the cooked dressing as they set over gentle heat, giving it body.
- Butter
- Adds richness and smooth mouthfeel to the dressing.
- Vinegar
- Adds acidity that balances the sweetness and richness of the dressing.
- Cream
- Mixed in after cooling to add softness and a lighter, creamier texture.
- Sugar
- Adds sweetness to balance the sharpness of the vinegar.
The step that matters
Cook the dressing over hot water until thickened. Egg proteins set as they heat, so cooking gently over hot water, rather than direct heat, helps the dressing thicken smoothly without curdling or scrambling. Stir constantly and stop once it coats a spoon.
Swap the nuts
How well each one fits the dish's main ingredients (banana, egg, sugar, mustard, vinegar, butter, cream):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against banana, egg, sugar, mustard, vinegar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
