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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Emulsify with the butter and spawn to give the sauce a smooth, thick body.
- Lobster spawn
- Adds rich lobster flavour and colour to the sauce base.
- Drawn butter or salad oil
- Supplies fat that carries flavour and gives the sauce a silky, rich texture.
- Butter
- Melted into the base to add richness and a glossy finish.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the fat.
- Lobster
- Stewed in the butter until tender, supplying the main flavour and texture of the dish.
The step that matters
Rub the egg and spawn mixture smooth. If the eggs are not worked smooth before the fat is added, the sauce can curdle or turn grainy. Eggs thicken as their proteins set, so lumps and uneven mixing give an uneven texture. Adding fat gradually keeps the emulsion stable.
Swap the mace
How well each one fits the dish's main ingredients (egg, lobster, mustard, butter, pepper, vinegar):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against egg, lobster, mustard, butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
