Why it works: Pepper and turmeric are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,478 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and brown to build a sweet, savory base for the soup.
- Bones from head and heel
- Stewing releases gelatin and flavor, giving the broth body and richness.
- Curry powder
- Blooms in hot butter to deliver the dish's main spiced aroma.
- Cayenne pepper
- Adds heat that sharpens the curry flavor.
- Harvey's sauce
- Adds a tangy, savory note stirred in at the end.
The step that matters
Frying the onions until brown. Flour coats the onions and they must brown in butter to develop deep, sweet flavor. Pale onions leave the soup flat, while over-browned ones turn bitter.
Swap the turmeric
The recipe marks turmeric as optional. How well each one fits the dish's main ingredients (meat, butter, onion, pepper, sauce):
- Garlicfits better
- Parsleyfits better
- Thymefits better
- Turmericthe original
Fit is the average pairing score against meat, butter, onion, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
