Why it works: Onion and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and sweetens as it fries, forming the base flavour of the sauce.
- Sour apple
- Adds tartness and body to the sauce as it softens and breaks down.
- Butter or lard
- Carries the curry powder's flavour and adds richness to the sauce.
- Curry powder
- Provides the main spice flavour and aroma of the dish.
- Water or stock
- Forms the liquid that the vegetables and spices simmer into a sauce.
The step that matters
Cook the sauce slowly for 30 minutes. A gentle, long simmer lets the onion and apple break down and the curry powder bloom, giving a smooth, well-developed sauce. Rushing it leaves the spices raw and the sauce thin.
Swap the apple
How well each one fits the dish's main ingredients (onion, vinegar, butter):
- Avocadofits better
