Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,030 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the base
In a stewpan, combine the sliced onions, garlic, and butter. Cook over low heat until softened.
Add the cut meat and season with salt and white pepper. Cover and simmer for 30 minutes.
Add the spices and finish
In a mortar, grind the turmeric, salt, cayenne, fenugreek, coriander seeds, and black pepper.
Add the ground spices and clear gravy to the stewpan. Simmer for another 30 minutes.
During the last 5 minutes, stir in the lime juice and a little flour or arrowroot to thicken.

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 slowly in butter, building the soup's flavour base.
- Butter
- Carries the aromatics and adds richness to the soup.
- Chickens or rabbit
- Provides the meat that simmers into the soup and enriches its body.
- Clear gravy
- Forms the liquid of the soup, carrying the spices through the simmer.
- Flour or arrowroot
- Thickens the soup as it finishes, giving it body.
- Lime juice
- Adds acidity that brightens the spiced, rich broth.
The step that matters
Adding the flour or arrowroot at the end. Starch thickens when heated in liquid but can clump if added raw or too early. Stirring it in during the last minutes, with the soup at a simmer, lets it thicken evenly without lumps or a pasty texture.

Fit is the average pairing score against onion, garlic, butter, chicken, lime, flour, turmeric. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
