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
Boil the eggs hard, then set aside to cool.
Make the curry sauce
In a saucepan, mix the butter and curry powder over moderate 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 a thick sauce.
Mix the cream with the flour, stir into the curry, and simmer until the raw taste is gone.
Finish and serve
Slice the boiled eggs in half.
Heat the sliced eggs in the sauce without boiling, and 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, served hot in the sauce.
- Butter
- Carries the curry powder and adds richness to the sauce.
- Curry powder
- Provides the main spiced flavour of the sauce.
- Onions
- Soften into the sauce, adding sweetness and body.
- Cream
- Adds richness and a smooth, mellow texture to the sauce.
- Wheat flour or rice flour
- Thickens the sauce so it clings to the eggs.
The step that matters
Simmer the cream and flour until the raw taste is gone. Flour mixed with cream stays pasty and tastes raw unless it is cooked for long enough. Simmering gelatinises the starch and cooks off the floury flavour, giving a smooth, properly thickened sauce.

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).
