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 ↓
Salad Dressing Without Cream or Oil
Ingredients
Directions
Make the base
Beat the egg whites.
Beat the egg yolks.
Combine the beaten whites and yolks.
Add salt, sugar, and mustard to the eggs.
Rub the butter and corn-starch together to form a cream.
Stir the butter-corn starch cream into the egg mixture.
Cook and finish
Place the bowl in a saucepan of hot water.
Stir constantly until the dressing thickens.
Remove the bowl from the heat.
Gradually pour in the vinegar while stirring continuously.
If the vinegar is too strong, dilute it with a little water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites and yolks thicken on gentle heat, giving the dressing its body.
- Butter
- Adds richness and smooths the texture of the dressing.
- Corn-starch
- Thickens the dressing as it heats, helping it hold together.
- Vinegar
- Supplies the sharp acidity that defines the dressing.
- Dry mustard
- Adds sharp flavor that balances the richness of the eggs and butter.
The step that matters
Stir constantly until the dressing thickens. Egg proteins set when heated, and over-heating or stopping to stir can cause them to curdle or scramble, leaving lumps instead of a smooth dressing.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, sugar, corn, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Asparagusfits about as well
- Potatofits about as well
Fit is the average pairing score against egg, butter, sugar, corn, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
