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
- Lobster spawn
- Gives the sauce its rich, briny flavour and colour.
- Drawn butter or salad oil
- Adds fat, carrying flavour and giving the sauce a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the flavour and cuts through the richness of the fat.
- Mustard
- Adds sharp, pungent flavour and helps emulsify the fat into the sauce.
- Lobster meat
- Provides the main protein and texture, softening as it stews in the sauce.
The step that matters
Stir in the fat slowly and keep the sauce smooth. Fat and vinegar-based liquids separate easily if added too quickly or left to overheat. Mustard acts as an emulsifier, helping the oil or butter bind into the liquid, so adding the fat gradually while stirring keeps the sauce smooth rather than greasy and split.
Swap the mustard
How well each one fits the dish's main ingredients (lobster, butter, pepper, vinegar, meat):
- Mustardthe original
- Capsicumfits about as well
- Shallotfits less well
- Potatofits less well
Fit is the average pairing score against lobster, butter, pepper, vinegar, meat. Candidates are from the same food group and used in at least 100 recipes.
