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 base
Melt butter in a pan and gently fry sliced onions, garlic, and eschalots until fine yellow-brown.
Drain the fried mixture on a sieve and transfer to a clean saucepan.
Simmer and strain
Add gravy and any optional ingredients like cocoa-nut or apples, and simmer for 30 to 45 minutes until onions are tender.
Strain the mixture through a strainer and bring it back to a boil.
Finish the curry gravy
Mix in curry powder, flour, and salt, then blend with cream to form a smooth batter.
Simmer for an additional 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 cook, forming the body of the gravy.
- Butter
- Carries the frying flavour and helps the onions brown gently.
- Gravy
- Provides the liquid base that the onions simmer in.
- Curry powder
- Supplies the spice and aroma that define the dish.
- Flour
- Thickens the gravy so it becomes a smooth batter-like sauce.
- Cream
- Adds richness and mellows the sauce's texture at the end.
The step that matters
Blending the flour and curry powder into the cream. Adding flour and cream to a boiling liquid can clump if not blended smooth first, so the sauce stays silky rather than lumpy.
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):
- Cinnamonfits better
- Nutmegfits better
- Turmericfits about as well
- Garlicthe original
Fit is the average pairing score against onion, butter, cocoa, apple, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
