Why it works: Butter and cream match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 41,494 recipes mention both. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Directions
Prepare the eggs
Boil the eggs hard.
Let the eggs 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 fry gently until soft.
Gradually pour in the broth or gravy and simmer until reduced to pulp.
Mix the cream with the flour.

Finish and serve
Slice the eggs into half-inch pieces.
Heat the eggs in the sauce without boiling.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main body of the dish and absorb the flavour of the sauce.
- Butter
- Carries the curry powder's aroma and adds richness to the sauce.
- Curry powder
- Provides the spiced flavour and aroma that defines the dish.
- Onions
- Soften into a sweet base that rounds out the sharpness of the curry.
- Thick cream
- Adds richness and a smooth, creamy texture to the sauce.
- Wheat flour or rice flour
- Thickens the sauce so it clings to the eggs.
The step that matters
Heat the eggs in the sauce without boiling. Boiling the sauce can toughen the egg whites and make the sauce separate or turn grainy. Gentle heat keeps the eggs tender and the cream smooth.

Fit is the average pairing score against egg, butter, cream, wheat. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
