Why it works: Mustard and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and spawn, giving the sauce a thick, smooth, creamy body.
- Lobster spawn
- Provides the main lobster flavor and a rich color to the sauce.
- Sweet oil
- Adds fat that carries flavor and gives the sauce a smooth, silky texture.
- Mustard
- Adds sharpness and helps the yolks and oil stay emulsified together.
The step that matters
Adding the oil slowly while mixing. Egg yolks can only hold oil in a stable emulsion when it is added gradually; adding it all at once can make the sauce split and look greasy. The record does not say how to add the oil, so this applies only if the oil is poured in with the other ingredients.
Swap the mustard
How well each one fits the dish's main ingredients (egg, lobster, pepper):

Fit is the average pairing score against egg, lobster, pepper. Candidates are from the same food group and used in at least 100 recipes.
