Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Curried Gravy
Ingredients
Directions
Prepare
Slice the onions, garlic, and eschalots (if using).
Fry and drain
Fry them gently in butter until they are a light brown.
Drain the fried mixture on a sieve.
Make the gravy
In a clean saucepan, combine the drained mixture with the gravy and cocoa-nut.
Simmer for 30 to 45 minutes until the onions are tender enough to strain.
Strain the gravy and bring it back to a boil.
Mix in the curry powder, flour, and salt to taste, combined with the cream.
Simmer for 15 to 20 minutes until ready to use.

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 and simmer, building the body of the gravy.
- Butter
- Fat for frying the onions, adding richness and browning them gently.
- Gravy
- Liquid base that carries the flavours and forms the body of the dish.
- Curry powder
- Supplies the spice blend that gives the gravy its characteristic aroma and flavour.
- Flour
- Thickens the gravy as it simmers, giving it a smoother, fuller texture.
- Cream
- Adds richness and softens the sharpness of the spices for a rounder finish.
The step that matters
Fry the onions gently to a light brown. Frying slowly caramelises the onion sugars for depth of flavour. Too much heat scorches them, leaving bitter notes that carry into the whole gravy.
Swap the clove
The recipe marks clove as optional. How well each one fits the dish's main ingredients (onion, garlic, butter, cocoa, flour, cream, vinegar):
- Turmericfits better
- Parsleyfits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against onion, garlic, butter, cocoa, flour, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
