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 the base
Slice the onions, garlic, and eschalots.
Fry them gently in butter until they are a fine yellow-brown.
Drain the fried mixture on a sieve.
Make the gravy
In a clean saucepan, combine the drained mixture with gravy and cocoa-nut (or other condiments) and simmer for 30 to 45 minutes until tender.
Strain the mixture and bring it back to a boil.
Add curry powder, flour, and salt, mixing to a smooth batter with cream.
Simmer for 15 to 20 minutes until ready to use.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Break down into a sweet, savoury base that gives the gravy its body.
- Butter
- Carries the frying of the aromatics and adds richness and browning.
- Gravy
- Forms the liquid base that the flavourings simmer in.
- Curry powder
- Supplies the spice and aroma that defines the dish.
- Flour
- Thickens the liquid so the gravy becomes smooth and coats the spoon.
- Cream
- Adds richness and softens the sharpness of the spices.
The step that matters
Adding the flour with the curry powder. Flour mixed into hot liquid can clump if not first worked smooth with cream or a little liquid. Mixing it to a smooth batter before it goes in lets it thicken evenly.
Swap the garlic
The recipe marks garlic as optional. How well each one fits the dish's main ingredients (onion, butter, cocoa, apple, flour, cream, vinegar):
- Cinnamonfits about as well
- Garlicthe original
- Nutmegfits about as well
- Turmericfits about as well
Fit is the average pairing score against onion, butter, cocoa, apple, flour, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
