Why it works: Vinegar and white pepper are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 1,154 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: acetic acid (sour, vinegar).
Egg and cream barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Lecithin in the yolks helps hold the oil and water together as a stable emulsion.
- Salad oil
- Forms the bulk of the sauce and gives it its rich, thick body.
- Vinegar
- Adds acidity that brightens flavor and balances the richness of the oil.
- Cream
- Adds smoothness and mild richness to the finished sauce.
The step that matters
Adding the salad oil. Oil must be added slowly while whisking so it breaks into fine droplets that the egg yolk can coat and suspend. Adding it too fast can overwhelm the yolk, and the emulsion breaks into a runny, separated sauce.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, vinegar, cream):
- Tarragonfits better
- Nutmegfits better
- Dillfits about as well
- White pepperthe original
Fit is the average pairing score against egg, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
