Why it works: Vinegar and mustard 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
- Oil
- Carries the seasonings and keeps the kidneys moist during cooking.
- Vinegar
- Adds acidity that sharpens the flavour of the dressing.
- Mustard
- Adds pungent flavour and helps the dressing cling to the kidneys.
The step that matters
Broil the kidneys until cooked through. Kidneys turn tough and rubbery if overcooked, so they need enough heat to cook through without drying out. Checking them as they cook helps avoid both raw centres and a chewy texture.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cabbagefits about as well
- Cucumberfits less well
Fit is the average pairing score against vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
