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
Fry the aromatics
Slice and gently fry the onions, garlic, and eschalots in butter until they are a fine yellow-brown.
Drain the fried mixture on a sieve and transfer to a clean saucepan.
Simmer and strain
Add the gravy and cocoa-nut (or other condiments) to the saucepan and simmer for 30 to 45 minutes until the onions are tender.
Strain the mixture and return it to the heat until it boils again.
Finish the curry
Mix in the curry powder, flour, and salt to taste, then blend with the cream to form a smooth batter.
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 during long simmering to give the gravy body and sweetness.
- Butter
- Carries the frying of the aromatics and adds richness and browning flavour.
- Curry powder
- Supplies the spice aroma that defines the dish.
- Flour
- Thickens the gravy so it becomes a smooth, coating batter.
- Cream
- Adds richness and softens the sharpness of the spices.
- Gravy
- Provides the savoury liquid base that the other ingredients simmer in.
The step that matters
Frying the onions to a fine yellow-brown. Gentle frying slowly converts the onions' sugars into browned, sweet flavour compounds. If they burn, the bitter taste carries into the whole sauce, and if they stay pale, the gravy lacks depth.
