Why it works: Arrowroot and lemon match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they cook, forming the body of the sauce.
- Curry powder
- Supplies the spiced aroma and flavour that defines the dish.
- Cream
- Adds richness and a smooth, mellow texture to the sauce.
- Arrowroot or rice flour
- Thickens the sauce to a glossy consistency without making it cloudy or floury.
- Hard boiled eggs
- Provide the main protein and a firm, creamy texture in the curry.
The step that matters
Heat the eggs thoroughly without boiling. Boiling the sauce after the eggs are added can toughen egg whites and make the cream separate or curdle. Gentle heat warms the eggs through while keeping the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (butter, cream, arrowroot, egg, lemon):
