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
Make the custard
Beat the yolks of eight eggs very light.
Place the other ingredients (except the cream and mustard) on the stove to heat.
When warm, add the eggs, stirring constantly until it comes to a boil, when it will be a smooth, thick custard.
When cold, add the mustard and cream.
Cook the yolks of three eggs, well beaten, with the mustard, salt, cayenne, sugar, melted butter or oil, cream or milk and hot vinegar in the double boiler until it thickens like soft custard.
Stir well.
Make the butter thickening
Boil half a cupful of vinegar with two teaspoonfuls of sugar.
Add a little salt, pepper and mustard, if you like.
Rub a quarter of a cupful of butter to a cream with one heaping teaspoonful of flour.
Pour the boiling vinegar on the butter and flour mixture.
Cook four or five minutes.
Pour the entire mixture over a well-beaten egg yolk.
Finish and cool
Turn this over one good pint of red or white chopped cabbage, and set away to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the dressing into a smooth custard as they cook and set with heat.
- Butter
- Adds richness and a silky body that softens the sharp vinegar.
- Flour
- Thickens the vinegar mixture so the dressing holds together without separating.
- Vinegar
- Provides the sharp acidity that balances the sweetness and richness of the dressing.
- Sugar
- Balances the acidity of the vinegar and rounds out the flavor.
- Cream
- Adds moisture and richness, softening the texture of the custard.
The step that matters
Stirring the eggs into the warm mixture. Egg proteins set when heated, so if the mixture gets too hot or is not stirred constantly, the eggs can scramble and leave lumps instead of a smooth custard.
