Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Curried Eggs
Ingredients

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, giving it a substantial, sliced texture.
- Butter
- Adds fat and richness, and helps the onion turn golden brown.
- Flour
- Thickens the liquid into a smooth, lightly bodied sauce.
- Curry powder
- Gives the sauce its spiced, aromatic flavour.
- Onion
- Adds savoury sweetness as it softens and browns in butter.
- White stock, cream, or milk
- Forms the liquid base of the sauce, adding moisture and body.
The step that matters
Adding the liquid to the flour mixture. Flour thickens liquid through its starch, which swells as it heats. Adding the stock, cream, or milk slowly while stirring spreads the flour evenly and prevents lumps, so the sauce ends up smooth rather than clumpy.
Swap the onion
How well each one fits the dish's main ingredients (egg, butter, flour, cream, pepper):
- Spinachfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
