Why it works: Butter and onion are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Curried Eggs
Ingredients
Directions
Prepare
Peel the hard-boiled eggs and set them aside to cool.
Make the curry sauce
In a saucepan, mix the butter and curry powder over medium heat for a few minutes.
Add the minced onions and sauté gently until soft.
Simmer the mixture until the raw taste of the curry is gone, without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish, set firm from boiling and holding their shape.
- Butter
- Carries the curry flavour and adds richness and a smooth, silky texture.
- Curry powder
- Supplies the spiced aroma and flavour that defines the dish.
- Onions
- Add sweetness and body as they soften, rounding out the spice.
The step that matters
Simmer without boiling. Curry powder tastes raw until its spices are gently heated in fat, and a hard boil can scorch the butter and onions, leaving a bitter or burnt taste. Gentle heat lets the flavour bloom evenly.
Swap the onion
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
