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 fry, forming the base of the curry sauce.
Cream
Adds richness and a smooth, creamy body to the sauce.
Arrowroot or rice flour
Thickens the cream into a smooth sauce without making it cloudy or gluey.
Hard-boiled eggs
Provide the main protein and substance of the dish, absorbing the curry flavour.

The step that matters

Heat thoroughly without boiling. Once the cream is thickened, a rolling boil can cause it to separate or curdle and can make the hard-boiled egg whites tough and rubbery. Gentle heat keeps the sauce smooth and the eggs tender.

Swap the arrowroot
