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 ↓
To Make Prepared Mustard

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground mustard
- Provides the main pungent flavour and the body of the condiment.
- Flour
- Thickens the paste and helps it hold a stiff, spreadable texture.
- Vinegar
- Adds acidity and thins the paste to the desired consistency.
The step that matters
Let the paste cool before adding vinegar. Heat can dull the sharp flavour of mustard, which develops when the ground mustard is mixed with cool liquid. Adding cold vinegar to a cooled paste keeps the pungency and lets you control the consistency.
Swap the mustard
How well each one fits the dish's main ingredients (flour, sugar, vinegar):

Fit is the average pairing score against flour, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
