Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Curry Sauce
Ingredients
Directions
Make the sauce
Cook the onion in the butter without browning.
Add the flour, curry powder, and salt mixed together; cook for 3-4 minutes.
Add the milk, white stock, currant jelly, and lemon juice; strain and reheat.
Optional nut or coconut milk
For coconut or almond milk, soak ½ cup of blanched almonds or coconut in 1½ cups of hot milk for at least an hour, then strain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the onion and fat-soluble curry flavour, and enriches the sauce.
- Flour
- Thickens the sauce as it cooks with the butter and milk.
- Curry powder
- Provides the main spiced flavour of the sauce.
- Milk
- Forms the liquid base that the flour thickens into a smooth sauce.
- Currant jelly
- Adds sweetness that balances the spices and acidity.
- Lemon juice
- Adds acidity that brightens the rich, spiced sauce.
The step that matters
Cook the flour and curry powder before adding liquid. Cooking the flour in fat for a few minutes cooks off raw starch taste and helps the sauce thicken smoothly without lumps. Stirring as liquid is added keeps the starch dispersed.
