Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
French Dressing
Ingredients
Directions
Make the base
Beat three tablespoonfuls oil, one-fourth teaspoonful salt, one tablespoonful vinegar, and one-half saltspoonful pepper together with a fork, then add vinegar slowly, beating well. Use at once, as the jelly soon separates.
Put into a cold bowl the yolks of three eggs and beat with a Dover beater until very light and thick.
Add one level teaspoonful mustard, one level teaspoonful salt, one saltspoonful sugar, one-half saltspoonful cayenne, and a few drops of oil.
Continue beating until too thick to turn the beater easily.
Finish the dressing
Add lemon juice to thin it, alternately with more oil, until two tablespoonfuls have been used; after that add vinegar to the same amount.
It will take about one pint of oil to make this amount stiff enough to hold its shape when dropped from a spoon.
At the last whip four tablespoonfuls of cream thick and stiff and beat into the sauce.
If the sauce is to be kept any length of time do not add the cream until just before using, or omit cream entirely, using just enough oil to make it of the right consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks emulsify the oil and vinegar, giving the dressing its thick body.
- Oil
- Forms the bulk of the emulsion, supplying richness and smooth texture.
- Vinegar
- Adds acidity that balances the richness of the oil and yolks.
- Mustard
- Helps stabilise the emulsion and adds a sharp, savoury bite.
- Cream
- Whipped in at the end to lighten the texture and add softness.
The step that matters
Adding the oil and lemon juice slowly. Oil must be added gradually to the beaten yolks so droplets disperse and the emulsion forms. Adding it too fast breaks the emulsion, leaving a thin, separated sauce.
