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
- Butter
- Melts into a rich fat base that carries the other flavours and coats the meat.
- Mustard
- Adds sharp, pungent flavour and helps emulsify the sauce into a paste-like base.
- Red pepper
- Adds heat and a warm, pungent bite to the sauce.
The step that matters
Stir the mustard paste into the melted butter. Mustard is mixed first into a paste so it disperses evenly; adding it dry or in lumps can leave pockets of harsh flavour and uneven texture in the sauce.
Swap the mustard
How well each one fits the dish's main ingredients (butter, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Onionfits less well
Fit is the average pairing score against butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
