Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Curried Eggs
Ingredients
Directions
Prepare the eggs
Boil the eggs for 10 minutes.
Transfer the eggs to cold water and remove the shells.
Cut off the ends of the eggs to allow them to stand upright.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 set firm when boiled.
- Milk
- Provides the liquid base that becomes the creamy curry sauce.
- Flour
- Thickens the milk mixture so the sauce becomes smooth and coats the eggs.
- Curry powder
- Supplies the spiced flavour that defines the sauce.
- Onion
- Softens in butter to add sweetness and body to the sauce.
- Butter
- Fat that softens the onion and carries the curry flavour.
The step that matters
Cook the mixture for 2 hours. Flour thickens only when the starch is heated enough to swell, and long simmering over low heat can scorch milk, so the sauce needs gentle, steady attention to stay smooth.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, sugar, flour, butter, lemon, pepper):
- Capsicumfits better
- Asparagusfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against egg, milk, sugar, flour, butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
