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 adds fat, helping keep the kidneys moist while they broil.
- Vinegar
- Adds acidity, giving the coating a sharp tang that balances the richness of the kidneys.
- Mustard
- Adds sharp flavour and helps the oil and vinegar blend into a more cohesive coating.
The step that matters
Broil the kidneys until cooked through. Kidneys turn tough and rubbery when overcooked, while undercooked kidneys are unsafe to eat. Watching them closely under the broiler keeps them tender and fully cooked.
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.
