Why it works: Vinegar and mustard 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 ↓
Fruit Salad Dressing
Ingredients
Directions
Make the base
Beat 2 eggs in a bowl until slightly beaten (use yolks of 4 eggs for a richer texture).
Add a little salt, cayenne pepper, dry mustard, 1 teaspoon sugar, and 1/2 teaspoon cornstarch; mix until very smooth.
Heat 4 tablespoons mild vinegar.
When hot, drop the vinegar little by little into the mixture in the bowl, beating all the time.
Cook and finish
Return to stove and stir until the mixture thickens.
Remove from stove and add 1 large tablespoon butter while hot; beat until very light and allow to cool.
When ready for use, add 1/2 cup cream whipped very stiff and stir into the dressing.

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 cook and give it a rich, smooth body.
- Vinegar
- Adds sharp acidity that balances the sweetness and richness of the dressing.
- Butter (in the method)
- Adds fat that softens the dressing and gives it a smooth, mellow mouthfeel.
- Cornstarch
- Helps thicken the mixture and stabilise it so it holds body when cooked.
- Cream (in the method)
- Adds lightness and moisture, making the finished dressing softer and airier.
The step that matters
Drop the hot vinegar in slowly while beating. Adding hot vinegar gradually while beating keeps the egg from scrambling into lumps, so the mixture stays 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.
